Let's go down to Kenneth in Virginia with 74 00:03:14,720 --> 00:03:18,240 Speaker 2: a fifteen Ford Fusion and well, a weird problem. Let's 75 00:03:18,240 --> 00:03:20,200 Speaker 2: talk about this, Kenneth. Welcome to the car, doctor, sir, 76 00:03:20,200 --> 00:03:20,800 Speaker 2: how can I help? 77 00:03:21,600 --> 00:03:23,000 Speaker 5: Yes, sir, thank you for having me. 78 00:03:23,040 --> 00:03:23,560 Speaker 3: You're welcome. 79 00:03:24,400 --> 00:03:27,840 Speaker 5: I have a twenty fifteen Ford Fusion, and about a 80 00:03:27,840 --> 00:03:31,440 Speaker 5: couple of years ago, the car was near e I 81 00:03:31,480 --> 00:03:33,400 Speaker 5: was just driving. I was doing some door dash uber 82 00:03:33,880 --> 00:03:36,120 Speaker 5: and all of a sudden the car started hesitating and 83 00:03:36,120 --> 00:03:39,960 Speaker 5: then just stopped. I was like, okay, wow, okay. But 84 00:03:40,000 --> 00:03:41,560 Speaker 5: then I just found out, okay, well, maybe that was 85 00:03:41,600 --> 00:03:45,120 Speaker 5: just because of lack of fuel fast forward. I took 86 00:03:45,120 --> 00:03:49,320 Speaker 5: it to Maynike and they got a reading from a 87 00:03:49,440 --> 00:03:51,400 Speaker 5: check engine light. And by the way, the check engine 88 00:03:51,440 --> 00:03:53,600 Speaker 5: light kept going off and on, but it was a 89 00:03:53,640 --> 00:03:57,960 Speaker 5: reading that the high fuel sensor needed to be replaced. 90 00:03:58,400 --> 00:04:01,880 Speaker 5: Them They replaced it, and then it started happening again 91 00:04:01,960 --> 00:04:05,640 Speaker 5: with the hesitation. Now this is what's fuel in it. 92 00:04:05,960 --> 00:04:07,560 Speaker 5: And then it was they said, oh, well, we got 93 00:04:07,560 --> 00:04:11,119 Speaker 5: to replace the low fuel sensor and then they replaced 94 00:04:11,120 --> 00:04:13,360 Speaker 5: that in the engine and then also said, oh, we 95 00:04:13,440 --> 00:04:16,400 Speaker 5: got to replace the field pump. And it was just 96 00:04:17,160 --> 00:04:20,839 Speaker 5: a whole bunch of things that were happening so ever 97 00:04:20,960 --> 00:04:23,880 Speaker 5: since then. I mean, it's been running really good, but 98 00:04:24,839 --> 00:04:28,320 Speaker 5: pass half a tank or in especially under a quarter 99 00:04:28,360 --> 00:04:30,880 Speaker 5: of a tank, either coming out of a stop line 100 00:04:31,000 --> 00:04:36,840 Speaker 5: or stop the signal, the car tends to hesitate, and 101 00:04:37,080 --> 00:04:40,599 Speaker 5: you know, I'll get a jerk like anything towards E 102 00:04:41,400 --> 00:04:44,360 Speaker 5: I'll get a jerk every once in a while, and 103 00:04:44,839 --> 00:04:47,480 Speaker 5: or after every time I get and I don't know 104 00:04:47,480 --> 00:04:50,320 Speaker 5: if this is a related issue. After I get gased, 105 00:04:52,600 --> 00:04:57,719 Speaker 5: maybe thirty seconds after I get gassed, they were the 106 00:04:57,800 --> 00:05:00,440 Speaker 5: car sends to one of the RPMs once to jump 107 00:05:00,520 --> 00:05:03,800 Speaker 5: up down again, and then it used to shut down 108 00:05:03,800 --> 00:05:06,080 Speaker 5: the car for a brief second. Then I have to 109 00:05:06,080 --> 00:05:08,920 Speaker 5: turn the car on and my Nike once again, they 110 00:05:08,920 --> 00:05:11,880 Speaker 5: were saying, oh, we'll check the perche valve, but no, 111 00:05:12,000 --> 00:05:12,799 Speaker 5: the perch valve. 112 00:05:12,720 --> 00:05:13,560 Speaker 6: Isn't the issue. 113 00:05:13,920 --> 00:05:18,240 Speaker 5: So they still feel that they have to keep running 114 00:05:18,279 --> 00:05:20,400 Speaker 5: tests and things like that. So I don't know if 115 00:05:20,400 --> 00:05:21,600 Speaker 5: those were related issues. 116 00:05:21,760 --> 00:05:23,320 Speaker 2: So let me let me ask Let me ask you 117 00:05:23,360 --> 00:05:26,719 Speaker 2: this Kenneth did. Did it sounds like and just correct 118 00:05:26,760 --> 00:05:28,919 Speaker 2: me if I'm wrong, But it sounds like the condition 119 00:05:29,040 --> 00:05:32,400 Speaker 2: or the problem changed after they put the fuel pump 120 00:05:32,400 --> 00:05:32,640 Speaker 2: in it. 121 00:05:34,560 --> 00:05:38,320 Speaker 5: Well, the fuel pump, well, I don't know if it 122 00:05:38,360 --> 00:05:41,240 Speaker 5: was what they kept saying. The sensors, the high flow 123 00:05:41,279 --> 00:05:44,040 Speaker 5: sensor and then the low field sensor, and they replaced it, 124 00:05:44,400 --> 00:05:47,000 Speaker 5: and then the fuel feel pump. But that was before 125 00:05:47,040 --> 00:05:49,200 Speaker 5: they replaced the fuel pump. They thought it was a 126 00:05:49,200 --> 00:05:51,280 Speaker 5: fuel pump issue. Okay, and I was getting a lot 127 00:05:51,279 --> 00:05:52,120 Speaker 5: of bad gas. 128 00:05:52,360 --> 00:05:56,200 Speaker 2: But also but also understand if you have a a 129 00:05:56,320 --> 00:06:00,640 Speaker 2: fault code for the high fuel pressure sensor, I I 130 00:06:00,920 --> 00:06:04,760 Speaker 2: don't know of any code in any car. Here's a 131 00:06:04,800 --> 00:06:07,960 Speaker 2: real blanket statement that you know. I don't think anybody 132 00:06:07,960 --> 00:06:10,239 Speaker 2: could prove wrong. I don't know of any fault code 133 00:06:10,279 --> 00:06:13,599 Speaker 2: of any car that it's it's it's a P zero 134 00:06:13,720 --> 00:06:17,480 Speaker 2: whatever and it says change that part. It's a it's 135 00:06:17,520 --> 00:06:21,840 Speaker 2: a it's a fault with the operating condition of that part. 136 00:06:22,640 --> 00:06:25,839 Speaker 2: In this case, it it. It's it flagged the high 137 00:06:25,920 --> 00:06:30,880 Speaker 2: fuel pressure sensor circuit because it saw an erroneous reading. 138 00:06:31,360 --> 00:06:33,240 Speaker 2: This could be a voltage problem, this could be a 139 00:06:33,240 --> 00:06:36,039 Speaker 2: ground problem, This could be a sensor problem. This could 140 00:06:36,040 --> 00:06:39,200 Speaker 2: be computer interpretation issue. This could be uh, you know, 141 00:06:39,240 --> 00:06:43,359 Speaker 2: a fuel pump fuel pump pressure circuit related issue. 142 00:06:43,760 --> 00:06:47,080 Speaker 3: Right, So did they jump the gun? 143 00:06:47,200 --> 00:06:52,000 Speaker 2: And my point becomes, is this different sense they worked 144 00:06:52,040 --> 00:06:56,040 Speaker 2: on it? Did they solve one problem or maybe create 145 00:06:56,200 --> 00:07:01,520 Speaker 2: another because of the quality or yeah, the quality of 146 00:07:01,520 --> 00:07:03,560 Speaker 2: the part itself? What are they missing? 147 00:07:04,640 --> 00:07:07,400 Speaker 5: Right? And so they they did the high flow sensor 148 00:07:07,480 --> 00:07:10,080 Speaker 5: first and then they did the low field pressure sensor 149 00:07:10,160 --> 00:07:13,000 Speaker 5: and that seemed to have worked better. After they have 150 00:07:13,200 --> 00:07:16,120 Speaker 5: replaced the low field sensors. Something was going on in 151 00:07:16,120 --> 00:07:19,080 Speaker 5: the engine where they felt like that was the key remedy, 152 00:07:19,600 --> 00:07:23,320 Speaker 5: but it didn't solve what it seemed like was sediment 153 00:07:23,360 --> 00:07:26,640 Speaker 5: in the gas tank. And I think at this at 154 00:07:26,640 --> 00:07:33,760 Speaker 5: this point, something's going on where the sediment keeps getting injected. 155 00:07:33,880 --> 00:07:36,320 Speaker 5: And so I've tried ce foam, I tried other things 156 00:07:36,360 --> 00:07:36,920 Speaker 5: on my own. 157 00:07:37,120 --> 00:07:39,320 Speaker 3: Well let's let's let's let's go back a step. 158 00:07:39,360 --> 00:07:41,600 Speaker 2: And you make a very good point, and you know, 159 00:07:41,840 --> 00:07:44,040 Speaker 2: are you always running the tank down low. 160 00:07:45,640 --> 00:07:47,520 Speaker 6: I used to Okay, I used to. 161 00:07:47,920 --> 00:07:49,360 Speaker 5: I don't do it as much anymore. 162 00:07:49,480 --> 00:07:53,200 Speaker 2: When they when they did the pump, did they happen 163 00:07:53,280 --> 00:07:55,200 Speaker 2: to mention did they look in the tank? Did they 164 00:07:55,200 --> 00:07:58,080 Speaker 2: come back and say, hey, Kenneth, the tank is spotlessly clean, 165 00:07:58,720 --> 00:08:00,680 Speaker 2: or gee, there's a bunch of right in there, let's 166 00:08:00,680 --> 00:08:04,000 Speaker 2: flush it out. Was there any commentary like that? 167 00:08:04,880 --> 00:08:07,440 Speaker 5: They did not say anything commentary. I think they were 168 00:08:07,440 --> 00:08:10,960 Speaker 5: grabbing at straws gas spring and saying, okay, well, we 169 00:08:11,080 --> 00:08:13,240 Speaker 5: still don't know. And then they try to relate it 170 00:08:13,240 --> 00:08:17,440 Speaker 5: to when I get gas, why does my RPM keep 171 00:08:17,520 --> 00:08:20,200 Speaker 5: jumping up? And wanted to shut the car after thirty 172 00:08:20,200 --> 00:08:21,520 Speaker 5: seconds after I get gassed. 173 00:08:21,600 --> 00:08:23,400 Speaker 3: So let's go, well, you're getting bad gas. 174 00:08:23,440 --> 00:08:26,080 Speaker 2: So let's let's well, yeah, you and everybody else. That's 175 00:08:26,080 --> 00:08:28,800 Speaker 2: why everybody's lined up with this same particular problem. Right, 176 00:08:29,160 --> 00:08:33,520 Speaker 2: So it's it's always bad gas, so first right, right, 177 00:08:33,600 --> 00:08:40,240 Speaker 2: absolutely under this problem is reproducible, correct, Like if you 178 00:08:40,280 --> 00:08:42,560 Speaker 2: brought it into another shop with a quarter tank of 179 00:08:42,559 --> 00:08:45,200 Speaker 2: fuel and they started driving it, at some point they're 180 00:08:45,240 --> 00:08:47,400 Speaker 2: going to experience this problem. 181 00:08:47,760 --> 00:08:50,080 Speaker 5: Yes, especially when I accelerate on the freeway. 182 00:08:50,120 --> 00:08:53,480 Speaker 2: I'm fine, okay, So why can't we Why can't we 183 00:08:54,000 --> 00:08:56,160 Speaker 2: let's go for heart rate and blood pressure, kiddo, Why 184 00:08:56,160 --> 00:08:57,959 Speaker 2: can't we hook up a scan tool, take this car 185 00:08:58,040 --> 00:09:00,800 Speaker 2: for a ride, pay for a diagnostic hour, and come 186 00:09:00,840 --> 00:09:03,520 Speaker 2: back and tell you, Hey, Kenneth, we watch fuel pressure 187 00:09:03,520 --> 00:09:06,600 Speaker 2: because we can see fuel pressure on a scan tool, right, 188 00:09:06,960 --> 00:09:09,199 Speaker 2: That's that's the purpose of the high fuel pressure low 189 00:09:09,200 --> 00:09:11,920 Speaker 2: fuel pressure sensors. That's the purpose of all that. We 190 00:09:11,960 --> 00:09:15,080 Speaker 2: can see fuel pressure readings visa via scan tool. What 191 00:09:15,240 --> 00:09:17,240 Speaker 2: sort of numbers do we get? Do they make sense? 192 00:09:17,320 --> 00:09:19,800 Speaker 2: Do we need to hook up and go look at 193 00:09:19,840 --> 00:09:22,480 Speaker 2: actual physical mechanical pressure on the low side? 194 00:09:23,000 --> 00:09:23,240 Speaker 3: Right? 195 00:09:24,120 --> 00:09:26,000 Speaker 2: We have a Do we have a problem with the 196 00:09:26,040 --> 00:09:29,000 Speaker 2: gd I pump, which is not completely uncommon? Do we 197 00:09:29,040 --> 00:09:32,160 Speaker 2: have something else creating this particular fault? 198 00:09:32,880 --> 00:09:35,440 Speaker 5: So, now, what about cleaning out the gas tank with 199 00:09:35,480 --> 00:09:36,160 Speaker 5: all the sediment? 200 00:09:36,360 --> 00:09:41,160 Speaker 2: Well, I mean we could surely take a sample of fuel. 201 00:09:41,520 --> 00:09:43,800 Speaker 2: That's easy enough. Now, we may not get what we 202 00:09:43,880 --> 00:09:46,920 Speaker 2: want out of the tank because of if it's on 203 00:09:47,000 --> 00:09:49,520 Speaker 2: the bottom, if it's true sediment, although you would think 204 00:09:49,559 --> 00:09:52,520 Speaker 2: if it's sediment and it somehow worked its way past 205 00:09:52,600 --> 00:09:54,640 Speaker 2: the sock that's supposed to be there and by sock 206 00:09:54,720 --> 00:09:58,360 Speaker 2: you understand what I'm saying. That's that little cylindrical screen 207 00:09:58,440 --> 00:10:01,000 Speaker 2: filter that's at the bottom of the to to prevent 208 00:10:01,440 --> 00:10:03,959 Speaker 2: muck from coming up. Right, you would think by now, 209 00:10:03,960 --> 00:10:06,240 Speaker 2: if it's truly picking up sediment, you would think by 210 00:10:06,240 --> 00:10:08,400 Speaker 2: now we would have chewed up the fuel pump, right 211 00:10:08,520 --> 00:10:12,360 Speaker 2: logical assumption, you know, would the fuel pump last three years? 212 00:10:12,360 --> 00:10:16,079 Speaker 2: I don't think so, but for sure, Listen, part of 213 00:10:16,080 --> 00:10:19,440 Speaker 2: the problem here is they haven't solved the issue, and 214 00:10:19,559 --> 00:10:22,160 Speaker 2: in my opinion, they're obligated to go back over what 215 00:10:22,240 --> 00:10:26,640 Speaker 2: they did, okay, and at least verify, Hey, is the 216 00:10:26,679 --> 00:10:29,040 Speaker 2: tank clean? If they didn't have the common sense to 217 00:10:29,080 --> 00:10:32,000 Speaker 2: look inside the tank, which you would think they did. 218 00:10:32,960 --> 00:10:35,560 Speaker 2: But you know, listen, we all as human beings scratch 219 00:10:35,600 --> 00:10:37,800 Speaker 2: our heads in the last couple of years about what's 220 00:10:37,840 --> 00:10:39,520 Speaker 2: going on in the world and around us and does 221 00:10:39,559 --> 00:10:43,120 Speaker 2: any common sense exist anymore? You know, if you take 222 00:10:43,160 --> 00:10:45,520 Speaker 2: the pump out, I would look inside and do I 223 00:10:45,559 --> 00:10:48,839 Speaker 2: see any crud, any sediment any because I want to 224 00:10:48,840 --> 00:10:49,960 Speaker 2: make sure that it is right. 225 00:10:50,760 --> 00:10:52,520 Speaker 3: So that's, you know, was that. 226 00:10:52,480 --> 00:10:54,280 Speaker 2: Mistake number one? They have to be able to answer 227 00:10:54,360 --> 00:10:57,680 Speaker 2: that question. You paid for a diagnosis, you paid for 228 00:10:57,720 --> 00:11:00,520 Speaker 2: a repair. It's either, guys. Either you're gonna work with 229 00:11:00,559 --> 00:11:02,680 Speaker 2: me and make this right. But I'm not here to 230 00:11:02,760 --> 00:11:04,880 Speaker 2: let you just continually run tests that may or may 231 00:11:04,920 --> 00:11:06,080 Speaker 2: not solve anything for me. 232 00:11:06,800 --> 00:11:09,160 Speaker 5: All right, Right, And that's been an over a year now, 233 00:11:09,480 --> 00:11:12,040 Speaker 5: and now the check engine light hasn't came on since 234 00:11:12,040 --> 00:11:15,959 Speaker 5: that incident. So this was this was December of twenty 235 00:11:15,640 --> 00:11:19,920 Speaker 5: twenty twenty four, so that check enguelight had never came 236 00:11:19,960 --> 00:11:22,520 Speaker 5: back gone. But my worry is like every time I 237 00:11:22,520 --> 00:11:27,160 Speaker 5: get gas or comet aut of out of a stop 238 00:11:27,240 --> 00:11:30,160 Speaker 5: sign or you know, I start to accelerate and then 239 00:11:30,200 --> 00:11:33,880 Speaker 5: the engine wants to to briefly just stop and sputter 240 00:11:34,400 --> 00:11:37,000 Speaker 5: for just a quick second. I'm thinking things, and I did, 241 00:11:37,080 --> 00:11:40,800 Speaker 5: and I once so forward they did a fuel engine cleaning, 242 00:11:41,480 --> 00:11:45,160 Speaker 5: you know for all that stuff. They're an engine cleaning stuff. 243 00:11:45,320 --> 00:11:47,800 Speaker 2: Well yeah, and that's not necessarily going to do anything 244 00:11:47,800 --> 00:11:49,360 Speaker 2: that's going to clean the engine, that's not going to 245 00:11:49,440 --> 00:11:52,280 Speaker 2: clean the tank. I think what you've got to do. 246 00:11:52,360 --> 00:11:53,600 Speaker 2: I think what you've got to do is go back 247 00:11:53,640 --> 00:11:55,240 Speaker 2: and talk to these guys. Listen, this has been going 248 00:11:55,240 --> 00:11:58,080 Speaker 2: on a year. Right, Either we're going to at least 249 00:11:58,120 --> 00:11:59,840 Speaker 2: go back and look at the take a fuel sample 250 00:11:59,880 --> 00:12:03,240 Speaker 2: and look at it right, and then at that point 251 00:12:03,360 --> 00:12:05,079 Speaker 2: decide what we're going to do next. But we've got 252 00:12:05,080 --> 00:12:06,960 Speaker 2: a baseline this and either get them to look at 253 00:12:06,960 --> 00:12:09,800 Speaker 2: it from a different angle or find another repair shop, 254 00:12:09,840 --> 00:12:12,240 Speaker 2: because I don't think these guys are rit do that. Kenneth, 255 00:12:12,240 --> 00:12:13,520 Speaker 2: give me a call back and we can kind of 256 00:12:13,520 --> 00:12:15,400 Speaker 2: talk about it from there on in. I'll be here 257 00:12:15,440 --> 00:12:17,000 Speaker 2: for you at eight five five five, six. 258 00:12:17,080 --> 00:12:19,400 Speaker 3: Nine nine zero zero. I'm ronning Andy and the car doctor. 259 00:12:19,440 --> 00:12:20,120 Speaker 3: Don't go anywhere. 260 00:12:33,800 --> 00:12:36,560 Speaker 2: Hey, let's go over and talk to Joe and South Jersey. 261 00:12:36,559 --> 00:12:39,120 Speaker 2: Oh six Toyota Matrix. Joe, you're the one that has 262 00:12:39,160 --> 00:12:42,480 Speaker 2: one left. So I haven't seen I haven't seen a matrix. God, 263 00:12:42,600 --> 00:12:45,200 Speaker 2: let's see, dirt was invented. I think back when I 264 00:12:45,200 --> 00:12:48,680 Speaker 2: saw the last matrix and uh, Tom Tom Ray had hair, 265 00:12:49,040 --> 00:12:51,080 Speaker 2: but uh, you know, it was a while ago. So 266 00:12:51,200 --> 00:12:52,160 Speaker 2: what's going on with this thing? 267 00:12:52,200 --> 00:12:53,400 Speaker 6: I'm very happy with that. 268 00:12:53,760 --> 00:12:54,320 Speaker 3: I'll tell you what. 269 00:12:54,600 --> 00:12:58,040 Speaker 2: Don't misunderstand me, brother, They were great cars, they really were, 270 00:12:59,080 --> 00:13:00,840 Speaker 2: you know, and you can always all the great cars 271 00:13:00,960 --> 00:13:03,600 Speaker 2: because the manufacturer stopped making them, they sell you something else. 272 00:13:03,920 --> 00:13:04,720 Speaker 3: You know it's rue. 273 00:13:04,760 --> 00:13:06,120 Speaker 2: You know, if we saw enough of these, we'll never 274 00:13:06,160 --> 00:13:07,559 Speaker 2: sell another car. So we've been to get rid of 275 00:13:07,559 --> 00:13:11,199 Speaker 2: the good ones. Just just an observation. So what's going on? 276 00:13:12,000 --> 00:13:16,080 Speaker 6: So lately I've had an intermittent uh problem with the 277 00:13:16,120 --> 00:13:20,880 Speaker 6: engine surging as if the accelerator was sticking. Okay, I 278 00:13:21,000 --> 00:13:22,960 Speaker 6: first I felt, well, maybe the carpet was sticking to 279 00:13:22,960 --> 00:13:25,600 Speaker 6: the excel under the accelerator. Took that out now, So 280 00:13:25,640 --> 00:13:28,880 Speaker 6: then I took it to my mechanic. They ran no 281 00:13:29,000 --> 00:13:31,400 Speaker 6: codes or anything else like that. They took it out 282 00:13:31,480 --> 00:13:33,840 Speaker 6: on the road for ro tests. Couldn't duplicate the problem. 283 00:13:34,040 --> 00:13:37,720 Speaker 3: Okay, So I'm at a loss higher mileage. 284 00:13:38,200 --> 00:13:40,240 Speaker 6: One hundred and eighty three thousand, all right. 285 00:13:40,600 --> 00:13:44,760 Speaker 3: So when it happens, is it? Tell me? Tell me? 286 00:13:45,000 --> 00:13:47,160 Speaker 2: Tell me when is it more likely to happen? Is 287 00:13:47,200 --> 00:13:50,840 Speaker 2: it dead cold, completely hot, or somewhere in between? 288 00:13:51,600 --> 00:13:52,520 Speaker 6: Somewhere in between. 289 00:13:52,960 --> 00:13:53,839 Speaker 3: Yeah, that's what I. 290 00:13:53,760 --> 00:13:59,280 Speaker 2: Thought you were going to say. And it can't easily 291 00:13:59,320 --> 00:14:01,480 Speaker 2: be reproduced. Or if I would have started from a 292 00:14:01,480 --> 00:14:04,880 Speaker 2: stone cold day like today and drive it until it 293 00:14:04,920 --> 00:14:08,600 Speaker 2: was warmed up, which might take till July, what I 294 00:14:09,559 --> 00:14:11,120 Speaker 2: experience the problem. 295 00:14:11,360 --> 00:14:12,680 Speaker 6: It may or may not happen. 296 00:14:12,920 --> 00:14:16,240 Speaker 2: Okay, what was not uncommon? And this is a one 297 00:14:16,280 --> 00:14:20,000 Speaker 2: point eight liter correct correct number one. I want to 298 00:14:20,000 --> 00:14:22,000 Speaker 2: look at fuel trim. I want to see where. I 299 00:14:22,000 --> 00:14:23,760 Speaker 2: want to see where fuel trim is when it's cold, 300 00:14:24,360 --> 00:14:26,160 Speaker 2: all right. I want to see how it's reacting and 301 00:14:26,200 --> 00:14:30,320 Speaker 2: what it's doing, because you know what's what's well, let's 302 00:14:30,320 --> 00:14:33,840 Speaker 2: talk about the simple stuff, all right. It'd be easy 303 00:14:33,880 --> 00:14:35,640 Speaker 2: to say, you know, if we were going to let 304 00:14:35,680 --> 00:14:37,960 Speaker 2: the internet diagnose this, they'll tell you it's a bad computer, 305 00:14:38,080 --> 00:14:40,400 Speaker 2: because computers go bad and that's what causes the problems. 306 00:14:40,400 --> 00:14:41,600 Speaker 2: And I got to tell you, out of all the 307 00:14:41,600 --> 00:14:45,120 Speaker 2: cars I work on, Toyota probably has the least amount 308 00:14:45,200 --> 00:14:48,560 Speaker 2: of failed engine processors and bcms and everything else. They 309 00:14:48,600 --> 00:14:52,680 Speaker 2: really do make a solid piece of electronics. So it 310 00:14:52,680 --> 00:14:56,320 Speaker 2: could be something goofy. For example, nobody ever thinks about 311 00:14:56,840 --> 00:14:57,760 Speaker 2: car has power. 312 00:14:57,560 --> 00:15:00,560 Speaker 3: Steering, right. 313 00:15:00,600 --> 00:15:03,440 Speaker 2: How about how about we watched the power steering switch 314 00:15:03,440 --> 00:15:06,760 Speaker 2: on a scan tool, and while we're driving along, does 315 00:15:06,800 --> 00:15:10,200 Speaker 2: the power steering switch chain state, which will alter how 316 00:15:10,240 --> 00:15:13,360 Speaker 2: the engine runs the idle or the idle air control 317 00:15:13,520 --> 00:15:18,000 Speaker 2: and bump engine speed trying to compensate for power steering load. 318 00:15:19,160 --> 00:15:20,480 Speaker 6: So you know it's interesting. 319 00:15:20,600 --> 00:15:22,480 Speaker 3: Yeah, it's I've had it twice. 320 00:15:23,040 --> 00:15:24,880 Speaker 2: I've had it twice on some of the toyotas, and 321 00:15:25,000 --> 00:15:27,880 Speaker 2: one was a matrix and one was a what was 322 00:15:27,920 --> 00:15:29,880 Speaker 2: the sister card of that, the camera or the Corolla 323 00:15:29,920 --> 00:15:33,200 Speaker 2: one of them. I forget which, but yeah, i've seen that. Yeah, Corolla, Right, 324 00:15:33,560 --> 00:15:36,120 Speaker 2: I've seen that. I've had that problem, which is an 325 00:15:36,120 --> 00:15:39,400 Speaker 2: odd ball nobody ever thinks about, but probably the most 326 00:15:39,440 --> 00:15:43,120 Speaker 2: common cause of what you're describing at that mid temperature 327 00:15:43,560 --> 00:15:47,520 Speaker 2: range between one hundred and thirty and one hundred and 328 00:15:47,520 --> 00:15:51,800 Speaker 2: seventy degrees of engine operation is going to be leaky 329 00:15:51,800 --> 00:15:55,120 Speaker 2: intake manifold gaskets. Have you put intake manifold gaskets on 330 00:15:55,160 --> 00:15:56,520 Speaker 2: this yet? No? 331 00:15:56,840 --> 00:15:59,600 Speaker 3: Oh, brother, you're overdue at. 332 00:15:59,520 --> 00:16:00,760 Speaker 6: Least I don't think so. But don't have to go 333 00:16:00,840 --> 00:16:02,120 Speaker 6: back and check my record, right. 334 00:16:02,040 --> 00:16:04,920 Speaker 2: Go back and check your records, because it would not 335 00:16:05,040 --> 00:16:08,120 Speaker 2: be uncommon. And at this point, just get it done. 336 00:16:08,160 --> 00:16:10,640 Speaker 2: It's it's it's it's an hour, maybe an hour and 337 00:16:10,680 --> 00:16:12,920 Speaker 2: a half. It's not terrible labor as long as the 338 00:16:12,960 --> 00:16:16,400 Speaker 2: thing still comes apart. And I would almost guarantee you 339 00:16:16,440 --> 00:16:19,480 Speaker 2: those round o rings are now crush square all right, 340 00:16:19,520 --> 00:16:22,840 Speaker 2: And what what happens is at that mid temperature range 341 00:16:23,640 --> 00:16:26,840 Speaker 2: the the O ring will you know, it'll space shuttle, 342 00:16:26,920 --> 00:16:29,120 Speaker 2: It'll contract a little bit and start to leak, and 343 00:16:29,200 --> 00:16:33,080 Speaker 2: oh boy, you know it plays havoc with fuel trim 344 00:16:33,320 --> 00:16:36,400 Speaker 2: because we're looking for a we're looking generally, we're looking 345 00:16:36,400 --> 00:16:38,560 Speaker 2: for an air leak here, we're looking for a vacuum 346 00:16:38,600 --> 00:16:41,320 Speaker 2: leak that all of a sudden occurred if the engine 347 00:16:41,320 --> 00:16:43,960 Speaker 2: started to if the engine, if an injector started to 348 00:16:44,760 --> 00:16:48,520 Speaker 2: somehow spray more fuel. What do you think the consequence 349 00:16:48,520 --> 00:16:48,880 Speaker 2: would be? 350 00:16:50,720 --> 00:16:53,920 Speaker 3: Well, would it's surgery? Would it stall? If you throw 351 00:16:53,960 --> 00:16:56,520 Speaker 3: it right, it would drown it out? Right? 352 00:16:57,640 --> 00:16:59,960 Speaker 2: If you fan a fly, if you fan a fire 353 00:17:00,200 --> 00:17:03,960 Speaker 2: with oxygen, it tends to flare up, right exactly. If 354 00:17:03,960 --> 00:17:06,840 Speaker 2: you add oxygen to the engine, it's gonna raise the 355 00:17:06,960 --> 00:17:09,360 Speaker 2: rpm a little bit, it's gonna go lean. And that's 356 00:17:09,359 --> 00:17:13,119 Speaker 2: why I'm looking at fuel trim. And you know, probably 357 00:17:13,240 --> 00:17:16,720 Speaker 2: the most common issue with these was the ability for 358 00:17:17,359 --> 00:17:20,280 Speaker 2: fuel trim to change as a result of leaky O 359 00:17:20,440 --> 00:17:23,159 Speaker 2: rings at the intake manifold all right. 360 00:17:24,480 --> 00:17:25,920 Speaker 6: But none of that would show up on a scan. 361 00:17:26,560 --> 00:17:27,399 Speaker 3: You might see it. 362 00:17:27,440 --> 00:17:29,199 Speaker 2: Well, I'll tell you what if you can get a 363 00:17:29,240 --> 00:17:31,800 Speaker 2: fault code to occur, or if you can watch fuel 364 00:17:31,840 --> 00:17:36,280 Speaker 2: trim all right, and you see fuel trim go excessively high, 365 00:17:36,520 --> 00:17:40,000 Speaker 2: up over nineteen twenty percent, and it's right at that 366 00:17:40,359 --> 00:17:43,000 Speaker 2: one hundred and sixty two degree mark. Don't ask me 367 00:17:43,000 --> 00:17:45,240 Speaker 2: why I remember that number, but I just it's it's 368 00:17:45,320 --> 00:17:47,720 Speaker 2: like right there, brother, If you can catch it right 369 00:17:47,720 --> 00:17:51,040 Speaker 2: at that moment, that's usually where you see it. When 370 00:17:51,040 --> 00:17:55,520 Speaker 2: it gets into the low one sixties, bang, and it'll 371 00:17:55,560 --> 00:17:58,280 Speaker 2: do play havoc with fuel trim. It'll play havoc with 372 00:17:58,359 --> 00:18:01,960 Speaker 2: engine speed idle the whole nine yards, and eventually it'll 373 00:18:01,960 --> 00:18:05,159 Speaker 2: set a lean fault code. That takes a while to 374 00:18:05,200 --> 00:18:07,080 Speaker 2: diagnose and figure out. But take a look at fuel 375 00:18:07,119 --> 00:18:09,159 Speaker 2: trim numbers and take a look at intake gaskets if 376 00:18:09,160 --> 00:18:11,560 Speaker 2: they haven't been done as maintenance. Maybe now is the 377 00:18:11,600 --> 00:18:13,880 Speaker 2: time I'm running any and the car doctor. We're back 378 00:18:14,000 --> 00:18:22,360 Speaker 2: right after this. All the city streets to the open 379 00:18:22,560 --> 00:18:23,320 Speaker 2: road tonight. 380 00:18:27,200 --> 00:18:27,639 Speaker 7: If you. 381 00:18:29,640 --> 00:18:33,280 Speaker 3: Run, we'll give you roll and ride. 382 00:18:47,520 --> 00:18:56,600 Speaker 2: Carrivison sounds a little like the Tabernacle choir you got 383 00:18:56,640 --> 00:18:59,879 Speaker 2: going on there, Tom. That's but that's very nice to 384 00:19:00,080 --> 00:19:02,480 Speaker 2: ban the band at least is working today, even though 385 00:19:02,480 --> 00:19:03,480 Speaker 2: my phone screen isn't. 386 00:19:03,480 --> 00:19:04,800 Speaker 3: But what the heck? Who cares? 387 00:19:05,119 --> 00:19:08,160 Speaker 2: So let's go where it's warm, Anderston. There's a hot 388 00:19:08,160 --> 00:19:10,040 Speaker 2: spell going up there in Ithaca, New York, where it's 389 00:19:10,080 --> 00:19:12,960 Speaker 2: minus three. At least it's not minus forty seven like 390 00:19:12,960 --> 00:19:15,879 Speaker 2: the poor folks up there at wat and upstate New 391 00:19:15,960 --> 00:19:18,000 Speaker 2: York or downstate New York, whichever the case might be. 392 00:19:18,040 --> 00:19:20,600 Speaker 2: Whoever you want to look at it, George, how can 393 00:19:20,640 --> 00:19:22,600 Speaker 2: I help you in your thirteen frontier today? Sir? 394 00:19:22,720 --> 00:19:23,360 Speaker 3: What's going on? 395 00:19:24,400 --> 00:19:25,560 Speaker 7: Thanks for taking the call. 396 00:19:25,680 --> 00:19:26,359 Speaker 3: You're welcome, sir. 397 00:19:27,200 --> 00:19:33,360 Speaker 7: It's insterious. Right. A few years ago it threw a 398 00:19:33,480 --> 00:19:36,399 Speaker 7: check engine lent code. A P four or five six 399 00:19:36,960 --> 00:19:43,600 Speaker 7: is a small ebat fleet right, stayed fine. I was 400 00:19:43,600 --> 00:19:47,360 Speaker 7: getting worried because it wouldn't pass inspection. And then it 401 00:19:47,880 --> 00:19:52,760 Speaker 7: went away and it stayed off for about four weeks. 402 00:19:53,240 --> 00:19:56,200 Speaker 7: I pulled it in quick, Oh, let's get in. I'll 403 00:19:56,200 --> 00:20:00,040 Speaker 7: get a sticker on it. Not worried about it. And 404 00:20:00,040 --> 00:20:04,000 Speaker 7: and about a month later it came back on and 405 00:20:04,040 --> 00:20:07,639 Speaker 7: it's done this now. This is the third time in 406 00:20:07,680 --> 00:20:12,399 Speaker 7: a row, right where you know it just sort of 407 00:20:12,640 --> 00:20:15,280 Speaker 7: it goes off and it stays off, and you know 408 00:20:15,400 --> 00:20:18,320 Speaker 7: they they put the scanner on it and it's there's 409 00:20:18,320 --> 00:20:24,200 Speaker 7: no codes pending. I have replaced a gas cap twice, 410 00:20:25,480 --> 00:20:30,600 Speaker 7: once after market once. Oh m, I've done the I've 411 00:20:31,359 --> 00:20:34,000 Speaker 7: you know, cleaned everything I could see. 412 00:20:34,720 --> 00:20:36,920 Speaker 2: Yeah, and let's stop. 413 00:20:36,960 --> 00:20:37,720 Speaker 3: Let's let's stop. 414 00:20:37,880 --> 00:20:41,119 Speaker 2: Let's stop doing gas caps here. Let's back up a second, George. 415 00:20:41,119 --> 00:20:45,720 Speaker 2: First of all, Nissan's strategy. Nissan loves their customers so 416 00:20:45,840 --> 00:20:48,240 Speaker 2: much that they've created a software strategy that if the 417 00:20:48,320 --> 00:20:51,639 Speaker 2: vehicle has a pending evaporative emission's fault, it will tell 418 00:20:51,680 --> 00:20:53,399 Speaker 2: you to check the gas cap because they don't want 419 00:20:53,440 --> 00:20:54,520 Speaker 2: you to think the car is broken. 420 00:20:55,680 --> 00:20:57,280 Speaker 7: Yeah, no, I figured that out. 421 00:20:57,400 --> 00:21:00,359 Speaker 2: Yeah, you know it's it's because God forbid the car 422 00:21:00,400 --> 00:21:02,440 Speaker 2: gets broken. Then they're afraid you might not want to 423 00:21:02,440 --> 00:21:04,720 Speaker 2: buy another one. However, if they told you the truth, 424 00:21:04,760 --> 00:21:06,919 Speaker 2: you might want to buy one. But that's you know, listen, 425 00:21:07,359 --> 00:21:09,399 Speaker 2: we can I only have a half hour left in 426 00:21:09,440 --> 00:21:10,080 Speaker 2: today's show, so. 427 00:21:10,040 --> 00:21:11,440 Speaker 3: I can't go on much further than that. 428 00:21:11,840 --> 00:21:14,080 Speaker 2: Let's let's let's talk about evapp a little bit. Can 429 00:21:14,080 --> 00:21:15,960 Speaker 2: we would you like to know how evapp systems work? 430 00:21:16,720 --> 00:21:17,520 Speaker 7: I would love to. 431 00:21:17,720 --> 00:21:20,679 Speaker 3: All right, you live in a house I do. You 432 00:21:20,720 --> 00:21:21,640 Speaker 3: got a front door. 433 00:21:23,320 --> 00:21:24,840 Speaker 7: And the back door cool. 434 00:21:25,040 --> 00:21:28,680 Speaker 2: All right, then you have an evapp system. So if 435 00:21:28,680 --> 00:21:31,560 Speaker 2: you took a five gallon can of gas and put 436 00:21:31,560 --> 00:21:34,320 Speaker 2: it out in your driveway and put the caps on 437 00:21:34,359 --> 00:21:36,200 Speaker 2: it and lift it in the sun, what's going to happen. 438 00:21:37,800 --> 00:21:40,720 Speaker 7: It's going to evaporate and I'll start smelling gas all 439 00:21:40,720 --> 00:21:41,280 Speaker 7: over the plate. 440 00:21:41,440 --> 00:21:44,240 Speaker 2: Well, in theory, but if the can was sealed, the 441 00:21:44,320 --> 00:21:45,400 Speaker 2: can would swell up. 442 00:21:45,520 --> 00:21:45,800 Speaker 6: Right. 443 00:21:46,359 --> 00:21:47,880 Speaker 7: If the can will swell. 444 00:21:47,680 --> 00:21:50,080 Speaker 3: Right, the can will swell so until. 445 00:21:49,840 --> 00:21:51,480 Speaker 7: It can't swell anymore. 446 00:21:51,080 --> 00:21:54,080 Speaker 2: Right, and then there's a loud noise. So you know 447 00:21:54,200 --> 00:21:56,840 Speaker 2: in theory, and automobile is a gas can, right, it's 448 00:21:56,880 --> 00:22:00,320 Speaker 2: got a gas tank. Yeah, right, So that vehicle sitting 449 00:22:00,359 --> 00:22:01,840 Speaker 2: out in the hot sun, they've got to have a 450 00:22:01,840 --> 00:22:04,840 Speaker 2: way to vent pressure in the tank and control fumes. 451 00:22:05,359 --> 00:22:07,160 Speaker 7: Okay, makes sense. 452 00:22:07,480 --> 00:22:11,280 Speaker 2: So there's a purge valve attached at the engine end 453 00:22:11,600 --> 00:22:15,400 Speaker 2: of the evaporative emissions system, and there is a vent 454 00:22:15,520 --> 00:22:19,000 Speaker 2: valve at the back of the vehicle attached to the 455 00:22:19,040 --> 00:22:22,440 Speaker 2: evaporative emissions system coming. 456 00:22:22,920 --> 00:22:25,280 Speaker 7: Where and the back is where the gas tank is. 457 00:22:25,400 --> 00:22:28,560 Speaker 2: Correct, So coming out of the coming out of the tank, 458 00:22:28,760 --> 00:22:32,199 Speaker 2: the vent line goes to the charcoal canister. Do you 459 00:22:32,200 --> 00:22:35,600 Speaker 2: have goldfish as a kid, Mama, lets you have fish? Right, 460 00:22:35,800 --> 00:22:39,080 Speaker 2: it went through a charcoal filter, right, kind of idea. 461 00:22:39,240 --> 00:22:43,120 Speaker 2: So they put fumes into the charcoal canister, that's where 462 00:22:43,160 --> 00:22:46,840 Speaker 2: it's stored for relief. At the proper time. Based on 463 00:22:46,960 --> 00:22:51,000 Speaker 2: ambient temperature, tank pressure, and some other factors, they will 464 00:22:51,040 --> 00:22:53,959 Speaker 2: open up the purge valve, meaning they will open up 465 00:22:53,960 --> 00:22:56,680 Speaker 2: the line that feeds the engine and the fumes from 466 00:22:56,760 --> 00:23:00,479 Speaker 2: the charcoal canister will be scavenger pulled into the engine 467 00:23:00,960 --> 00:23:03,280 Speaker 2: to be consumed to help control. 468 00:23:02,920 --> 00:23:05,680 Speaker 7: So that they burn up with everything else, right, So. 469 00:23:05,640 --> 00:23:07,919 Speaker 2: The canister doesn't get overloaded, it doesn't get what we 470 00:23:07,960 --> 00:23:11,920 Speaker 2: say saturated, all right, at certain times, at certain times 471 00:23:11,920 --> 00:23:14,280 Speaker 2: they will open up the vent so the purge has 472 00:23:14,320 --> 00:23:17,080 Speaker 2: an easier job of scavenging. You ever have to put 473 00:23:17,119 --> 00:23:18,880 Speaker 2: fresh air in the house, you open up the front door, 474 00:23:18,920 --> 00:23:20,040 Speaker 2: you don't get a lot of airflow. 475 00:23:20,040 --> 00:23:21,440 Speaker 3: What do you do? You open up the back door 476 00:23:21,440 --> 00:23:24,160 Speaker 3: and now the air can move through right now? Yeah, right, 477 00:23:24,240 --> 00:23:24,680 Speaker 3: same thing. 478 00:23:24,800 --> 00:23:26,120 Speaker 2: Or you open up the back door and you open 479 00:23:26,200 --> 00:23:27,760 Speaker 2: up the front and it goes that way. You know, 480 00:23:27,800 --> 00:23:29,480 Speaker 2: it's the same idea, front door. 481 00:23:29,320 --> 00:23:32,480 Speaker 7: Back just like just like popping the vent on the 482 00:23:32,800 --> 00:23:34,639 Speaker 7: gas tank for an outboard motor. 483 00:23:34,840 --> 00:23:41,440 Speaker 2: Correct, absolutely right, So you're looking for an evaporative emissions leak. 484 00:23:41,520 --> 00:23:43,800 Speaker 2: A P zero four fifty six is a leak that 485 00:23:43,880 --> 00:23:46,199 Speaker 2: will move a vacuum gage or the bubble on the 486 00:23:46,240 --> 00:23:48,800 Speaker 2: machine less than twenty thousands of an inch. So it's 487 00:23:48,800 --> 00:23:50,520 Speaker 2: about the thickness of a hair on your head. 488 00:23:51,680 --> 00:23:52,640 Speaker 3: All right, we're looking. 489 00:23:53,800 --> 00:23:57,000 Speaker 2: Well, yeah, I get it, but it's it's it's it's 490 00:23:57,119 --> 00:24:00,159 Speaker 2: it's a pimple on a fly's butt. All right, You're 491 00:24:00,240 --> 00:24:03,040 Speaker 2: you're looking for a real small leak. Now, you can 492 00:24:03,080 --> 00:24:08,159 Speaker 2: look for this by connecting a smoke machine, going to 493 00:24:08,240 --> 00:24:13,040 Speaker 2: the vent valve and sealing the vent. Usually I stick 494 00:24:13,080 --> 00:24:16,200 Speaker 2: my finger in the vent lineh and and it goes 495 00:24:16,240 --> 00:24:18,280 Speaker 2: and I watch, you know. Or I'll put I'll put 496 00:24:18,280 --> 00:24:20,600 Speaker 2: a rubber hose with a plug, I'll put the smoke 497 00:24:20,680 --> 00:24:23,200 Speaker 2: machine in at the purge and I'll fill the system 498 00:24:23,320 --> 00:24:26,119 Speaker 2: and I'll watch and I'll see does the machine, the 499 00:24:26,160 --> 00:24:29,800 Speaker 2: smoke machine show me no flow. And I've got a 500 00:24:29,800 --> 00:24:31,720 Speaker 2: bunch if you go to my YouTube channel. As a 501 00:24:31,720 --> 00:24:34,440 Speaker 2: matter of fact, I've got a bunch of videos using 502 00:24:34,440 --> 00:24:37,600 Speaker 2: my red line smoke detection machine and it will show 503 00:24:37,640 --> 00:24:40,119 Speaker 2: you and explain EVAP system in greater detail, in a 504 00:24:40,160 --> 00:24:42,679 Speaker 2: greater length. But it's the idea that you may not 505 00:24:42,760 --> 00:24:45,440 Speaker 2: be able to see this leak by the naked eye, 506 00:24:45,480 --> 00:24:48,880 Speaker 2: and chances are you can't now the fact that you're 507 00:24:48,880 --> 00:24:51,800 Speaker 2: in Ithaca. You get this stuff called snow. I'm sure 508 00:24:51,840 --> 00:24:54,600 Speaker 2: you're familiar with it. They put these, they put these, 509 00:24:54,760 --> 00:24:57,399 Speaker 2: you know, chemicals on the road to help reduce the 510 00:24:57,440 --> 00:25:00,919 Speaker 2: amount of snow that also creates this stuff called rust. 511 00:25:02,240 --> 00:25:05,280 Speaker 2: You know, are any are any of the steel lines 512 00:25:05,320 --> 00:25:08,760 Speaker 2: which were one steel now crumbling rust? Are any of 513 00:25:08,800 --> 00:25:11,160 Speaker 2: those porous to the point that they're creating a leak? 514 00:25:12,320 --> 00:25:15,320 Speaker 2: So all of this has to be considered. No, you 515 00:25:15,400 --> 00:25:17,960 Speaker 2: won't get a fuel smell. No you won't see puddles 516 00:25:18,000 --> 00:25:21,359 Speaker 2: because we're dealing with fumes and we're dealing again with 517 00:25:21,440 --> 00:25:22,960 Speaker 2: a pinhole somewhere. 518 00:25:23,280 --> 00:25:28,160 Speaker 3: Right, So you know my guess. 519 00:25:28,200 --> 00:25:32,480 Speaker 2: I generally tell everybody most EVAP leaks diagnosed within the hour, 520 00:25:32,800 --> 00:25:35,480 Speaker 2: done properly with a good smoke machine. And once you 521 00:25:35,520 --> 00:25:37,480 Speaker 2: take a look at my videos on my YouTube channel, 522 00:25:37,480 --> 00:25:40,600 Speaker 2: you'll understand what I'm saying. If they can't be diagnosed 523 00:25:40,600 --> 00:25:44,160 Speaker 2: with smoke. Then we're going to talk about using nitrogen, 524 00:25:45,240 --> 00:25:48,320 Speaker 2: all right, or we're going to talk about using carbon 525 00:25:48,359 --> 00:25:52,360 Speaker 2: dioxide a CO two indicator and reading it that way. 526 00:25:52,400 --> 00:25:54,880 Speaker 2: But that's a little bit of a different scenario, all right. 527 00:25:55,440 --> 00:25:59,240 Speaker 2: Usually the Nissans, the two areas of concern are the 528 00:25:59,359 --> 00:26:02,680 Speaker 2: vent valve or the steel lines in the back generally 529 00:26:02,760 --> 00:26:06,119 Speaker 2: rot and they get porous over time, and they can 530 00:26:06,119 --> 00:26:07,280 Speaker 2: create a pinhole leak. 531 00:26:08,400 --> 00:26:11,679 Speaker 7: Now, there's certainly a lot of salt, right, and I 532 00:26:11,680 --> 00:26:13,760 Speaker 7: can believe, I mean, as much as you try and 533 00:26:13,800 --> 00:26:14,359 Speaker 7: watch it. 534 00:26:14,280 --> 00:26:16,159 Speaker 3: Off right, you can't. 535 00:26:16,560 --> 00:26:20,640 Speaker 2: And then up front under the hood, anywhere you see 536 00:26:20,720 --> 00:26:25,000 Speaker 2: plastic tubing going into a rubber fitting on a twenty 537 00:26:25,119 --> 00:26:30,120 Speaker 2: thirteen anything, you know, Chrysler Jeep four GM, I don't care. 538 00:26:29,960 --> 00:26:30,439 Speaker 3: What it is. 539 00:26:31,160 --> 00:26:33,879 Speaker 2: If I can twist that little hard plastic tube and 540 00:26:33,920 --> 00:26:39,040 Speaker 2: the rubber fitting, yeah, suspect of that too, all right, 541 00:26:39,680 --> 00:26:42,159 Speaker 2: And I'm gonna take a look at that and consider that. 542 00:26:42,280 --> 00:26:45,119 Speaker 2: So there's a bunch of things it's not impossible to fix. 543 00:26:45,760 --> 00:26:48,639 Speaker 2: The reason it may show up more predominantly in cold 544 00:26:48,680 --> 00:26:50,720 Speaker 2: weather versus warm is why. 545 00:26:52,760 --> 00:26:55,200 Speaker 3: In cold weather things contract. 546 00:26:54,800 --> 00:26:58,639 Speaker 2: Right, So when they contract, you know, Oh and so 547 00:26:58,720 --> 00:27:02,760 Speaker 2: if it's loose, right, and then when it's warm. When 548 00:27:02,800 --> 00:27:06,560 Speaker 2: it's warm, it swells. So you know, that's the kind 549 00:27:06,560 --> 00:27:09,000 Speaker 2: of diagnosis you've got to go through. But that's evapp 550 00:27:09,240 --> 00:27:12,679 Speaker 2: and how to look at it in a nutshell. All right, George, 551 00:27:12,920 --> 00:27:16,040 Speaker 2: I I gotta go, brother, I'm up against the clock. 552 00:27:16,080 --> 00:27:16,560 Speaker 3: But you do that. 553 00:27:16,600 --> 00:27:18,239 Speaker 2: Get a look at my YouTube channel. There's a lot 554 00:27:18,240 --> 00:27:20,040 Speaker 2: of information there. Go look at some of the evapp 555 00:27:20,119 --> 00:27:22,520 Speaker 2: videos if you need more. I'll be back next weekend. 556 00:27:22,600 --> 00:27:23,600 Speaker 2: I'm running ady in the car. 557 00:27:23,640 --> 00:27:40,560 Speaker 3: Doctor. I'll be back right after this. Hey, let's get going. 558 00:27:40,640 --> 00:27:44,080 Speaker 2: Let's go over to New Mexico, Stefan and see what's 559 00:27:44,119 --> 00:27:48,120 Speaker 2: going on here. O five Rangers, Good sir, what's going on? 560 00:27:49,000 --> 00:27:51,399 Speaker 8: Well, I've been chasing a small evapp league for the 561 00:27:51,400 --> 00:27:52,639 Speaker 8: better part of two years. 562 00:27:52,640 --> 00:27:56,480 Speaker 2: Oh boy, it's evap power. That's okay. 563 00:27:57,600 --> 00:27:58,400 Speaker 3: So what are you using? 564 00:27:58,480 --> 00:28:00,600 Speaker 2: And you know it's a p V zero four fifty six. 565 00:28:00,880 --> 00:28:02,600 Speaker 2: Is it constant or does it come and go? 566 00:28:03,520 --> 00:28:07,320 Speaker 8: It's a four four two actually, and it has been. 567 00:28:07,520 --> 00:28:09,520 Speaker 8: It's been pretty constant over the past couple of years. 568 00:28:09,560 --> 00:28:11,240 Speaker 8: I've had a mechanic replace a couple of things that 569 00:28:11,280 --> 00:28:15,720 Speaker 8: I couldn't do from the canister valve or the canister 570 00:28:16,000 --> 00:28:18,200 Speaker 8: purge canister all the way up to a new gas tank. 571 00:28:18,480 --> 00:28:18,840 Speaker 3: Okay. 572 00:28:19,440 --> 00:28:21,800 Speaker 8: I remember hearing you talk on a on like an 573 00:28:21,880 --> 00:28:24,159 Speaker 8: archive show about you know, it being one thing and 574 00:28:24,200 --> 00:28:26,200 Speaker 8: then it being in another thing, and you know, maybe 575 00:28:26,240 --> 00:28:29,960 Speaker 8: both things were wrong. And you know, I was told 576 00:28:29,960 --> 00:28:31,960 Speaker 8: that it could be simple as like a purge canister 577 00:28:32,119 --> 00:28:37,719 Speaker 8: or a valve, and replaced those and smoke tests revealed nothing. 578 00:28:38,040 --> 00:28:40,440 Speaker 8: A second smoke test was like, we got a small 579 00:28:40,520 --> 00:28:42,920 Speaker 8: leak on top of the gas tank, replaced the gas tank. 580 00:28:43,600 --> 00:28:47,240 Speaker 8: Now that it's cold, the codes back, so I'm still 581 00:28:47,320 --> 00:28:47,960 Speaker 8: hunting for it. 582 00:28:48,040 --> 00:28:49,120 Speaker 3: Okay, So. 583 00:28:51,200 --> 00:28:54,640 Speaker 2: Yeah, and I know it's painful, right it is. You know, 584 00:28:54,960 --> 00:28:57,520 Speaker 2: when we do the smoke test, they find nothing correct. 585 00:28:58,160 --> 00:29:00,360 Speaker 8: That's correct, and we've done too. Although he said that 586 00:29:00,400 --> 00:29:02,000 Speaker 8: they found a tiny week in the gas thing, so 587 00:29:02,040 --> 00:29:05,000 Speaker 8: maybe it was there two things on top of each other. 588 00:29:05,080 --> 00:29:08,040 Speaker 2: Listen, there's no rule that says it's only one thing, right, 589 00:29:08,440 --> 00:29:10,720 Speaker 2: So if if you can prove one thing is bad, 590 00:29:10,800 --> 00:29:13,040 Speaker 2: change it and go on to the next thing. You know, 591 00:29:13,240 --> 00:29:15,800 Speaker 2: I'm working with a gentleman John I think he's in Michigan, 592 00:29:15,840 --> 00:29:19,840 Speaker 2: who's got a break problem on his son's focus or fusion, 593 00:29:20,440 --> 00:29:23,560 Speaker 2: and we prove the HCU unit bad and now we're 594 00:29:23,560 --> 00:29:25,880 Speaker 2: working we're diving into a little bit other part of 595 00:29:25,880 --> 00:29:27,840 Speaker 2: the system, a little bit deeper. So it's just you know, 596 00:29:28,120 --> 00:29:29,440 Speaker 2: you know, fix what you know is bad, go on 597 00:29:29,480 --> 00:29:30,120 Speaker 2: to the next thing. 598 00:29:31,240 --> 00:29:31,440 Speaker 5: You know. 599 00:29:32,200 --> 00:29:37,120 Speaker 2: Keep in mind a smoke test. Smoke creates pressure, so 600 00:29:37,360 --> 00:29:40,360 Speaker 2: it's it's real low. It's probably less than half a pound, 601 00:29:40,480 --> 00:29:44,920 Speaker 2: but it can create pressure. So if I'm working with 602 00:29:44,960 --> 00:29:50,760 Speaker 2: a problem vehicle that's got this random EVAPP issue, you know, yeah, 603 00:29:50,920 --> 00:29:54,080 Speaker 2: purge event. Sometimes it's quicker and easier, a good quality part, 604 00:29:54,160 --> 00:29:57,120 Speaker 2: whatever it might be. I like the idea of the tank, 605 00:29:57,600 --> 00:29:59,240 Speaker 2: you know, I would like to run the test again. 606 00:30:00,040 --> 00:30:03,959 Speaker 2: Did it did it you know, did it reoccur? You know, 607 00:30:04,320 --> 00:30:08,200 Speaker 2: with everything replaced, clear the codes run the vehicle, does 608 00:30:08,240 --> 00:30:10,560 Speaker 2: the system run its monitor and pass its test? 609 00:30:11,920 --> 00:30:13,960 Speaker 8: Uh? Yeah, Well it was for a long time, so 610 00:30:14,000 --> 00:30:16,080 Speaker 8: when we replaced the UH, it would usually come back 611 00:30:16,120 --> 00:30:17,880 Speaker 8: pretty quick, you know, like one cycle, and it would 612 00:30:17,920 --> 00:30:19,840 Speaker 8: come back right after we did. After we did the 613 00:30:19,840 --> 00:30:22,600 Speaker 8: gas tank, everything's been fined for months and I thought 614 00:30:22,640 --> 00:30:25,320 Speaker 8: it was gone, but then now that it's cold, it's back. 615 00:30:25,360 --> 00:30:27,080 Speaker 8: So I feel like it's like a hose or like 616 00:30:27,120 --> 00:30:31,160 Speaker 8: a fitting, right, I get I get a gas smell occasionally. 617 00:30:30,760 --> 00:30:33,240 Speaker 3: Right where front of the vehicle, back of the vehicle. 618 00:30:34,320 --> 00:30:36,640 Speaker 8: I would say fronts because I'm smelltt it in the cab. 619 00:30:36,960 --> 00:30:39,920 Speaker 2: What's what's what's where's the The canister is in the 620 00:30:40,120 --> 00:30:41,080 Speaker 2: left front rail. 621 00:30:42,080 --> 00:30:42,200 Speaker 6: Uh. 622 00:30:42,480 --> 00:30:43,880 Speaker 8: I believe that's correctly right. 623 00:30:44,360 --> 00:30:47,800 Speaker 2: So going into the canister, we've got some I'm trying 624 00:30:47,800 --> 00:30:50,120 Speaker 2: to remember what O five looks like. Plastic tubing and rubber, 625 00:30:50,520 --> 00:30:52,360 Speaker 2: rubber hoses, rubber connections. 626 00:30:52,640 --> 00:30:54,280 Speaker 8: There's a lot of plastic and rubbery. 627 00:30:54,560 --> 00:30:58,120 Speaker 2: Could we could we have something there shrinking contracting if 628 00:30:58,160 --> 00:31:01,880 Speaker 2: we were too simply It sounds a little archaic, but 629 00:31:01,920 --> 00:31:04,520 Speaker 2: A five is twenty one years old. We're probably not 630 00:31:04,560 --> 00:31:07,040 Speaker 2: going to find a lot of parts anymore. If we 631 00:31:07,040 --> 00:31:10,560 Speaker 2: were to carefully pull apart at the canister and take 632 00:31:10,600 --> 00:31:14,160 Speaker 2: those little plastic sleeves out of the rubber bushings and 633 00:31:14,400 --> 00:31:19,680 Speaker 2: RTV im in. Yeah, you know, I like to seal 634 00:31:19,720 --> 00:31:21,960 Speaker 2: them and you know, give me a little bit of 635 00:31:21,960 --> 00:31:26,040 Speaker 2: our TV just for giggles. If the problem is there 636 00:31:26,120 --> 00:31:27,640 Speaker 2: right now, I want you to pull the line off 637 00:31:27,640 --> 00:31:31,560 Speaker 2: at the purge valve started up disconnected electrically start it up, 638 00:31:31,960 --> 00:31:35,600 Speaker 2: wet your finger and against the and do you feel 639 00:31:35,640 --> 00:31:36,280 Speaker 2: engine suction? 640 00:31:37,120 --> 00:31:37,400 Speaker 3: Right? 641 00:31:37,960 --> 00:31:41,720 Speaker 2: There's there's there's no rule that says the new part's 642 00:31:41,760 --> 00:31:46,160 Speaker 2: still good, you know. And testing a bad purge valve 643 00:31:46,240 --> 00:31:48,040 Speaker 2: is one of the quickest and easiest things you can do. 644 00:31:48,760 --> 00:31:51,000 Speaker 2: Usually it's with a rubber glove on because a rubber 645 00:31:51,000 --> 00:31:53,880 Speaker 2: glove is a little more ceiling. I get a little 646 00:31:53,920 --> 00:31:57,440 Speaker 2: wet and and if I feel suction against my finger, 647 00:31:57,880 --> 00:32:01,720 Speaker 2: the new part's bad. It doesn't take much right now, 648 00:32:02,000 --> 00:32:04,440 Speaker 2: Now you could sit there and look at it. If 649 00:32:04,440 --> 00:32:07,320 Speaker 2: it's random and intermittent, right, you know, how does the 650 00:32:07,360 --> 00:32:08,920 Speaker 2: system know of if the purge vows leaking? 651 00:32:08,960 --> 00:32:10,680 Speaker 3: Do you ever think about this? What does it look at? 652 00:32:12,000 --> 00:32:15,600 Speaker 8: Uh? Yeah, I don't know, maybe like maybe pressure somewhere 653 00:32:15,760 --> 00:32:16,360 Speaker 8: they tell you what. 654 00:32:16,400 --> 00:32:18,240 Speaker 2: Let me pull over, take the pause. When I come back, 655 00:32:18,560 --> 00:32:20,400 Speaker 2: we'll give you that answer for you and everybody else. 656 00:32:20,400 --> 00:32:22,320 Speaker 3: I'm running any in the car. Doctor. We'll return right 657 00:32:22,320 --> 00:32:37,320 Speaker 3: after this. Hey, and here we go. Let's go back 658 00:32:37,320 --> 00:32:38,400 Speaker 3: to Stefan and New Mexico. 659 00:32:38,480 --> 00:32:42,600 Speaker 2: You're there, sure, So we're gonna look at fuel tank 660 00:32:42,720 --> 00:32:44,080 Speaker 2: pressure sensor FTP. 661 00:32:44,280 --> 00:32:45,239 Speaker 3: You ever wonder what that is? 662 00:32:46,400 --> 00:32:48,760 Speaker 8: Uh? You will. I feel like I should have had 663 00:32:48,840 --> 00:32:50,680 Speaker 8: gotten a new one. Woman got the new gas sank. 664 00:32:50,840 --> 00:32:53,920 Speaker 2: Well, you would hope, right, you know you would. You 665 00:32:53,960 --> 00:32:57,040 Speaker 2: would hope that it's sealed well. And FTP is just 666 00:32:57,080 --> 00:32:59,320 Speaker 2: what it says. It's fuel tank pressure or fuel tank 667 00:32:59,360 --> 00:33:02,280 Speaker 2: state of vacuum or fuel tank state of change. Right, 668 00:33:02,680 --> 00:33:04,200 Speaker 2: you got an OBD two scan tool. 669 00:33:05,040 --> 00:33:06,800 Speaker 8: I do not, but I'm in the market for one. 670 00:33:06,840 --> 00:33:09,040 Speaker 2: Now, Okay, so you know, let's let's let's get let's 671 00:33:09,080 --> 00:33:11,880 Speaker 2: if you can get something your make model, that's even better. Right, 672 00:33:11,960 --> 00:33:15,320 Speaker 2: but let's let's plug in. Let's bring up FTP fuel 673 00:33:15,320 --> 00:33:19,280 Speaker 2: tank pressure sensor, right or tank pressure sensor. Turn the keyon, 674 00:33:19,360 --> 00:33:22,600 Speaker 2: engine off, go look at it all, right, You'll see 675 00:33:22,760 --> 00:33:24,920 Speaker 2: you'll see voltage. Let's say you're going to see two 676 00:33:24,960 --> 00:33:27,160 Speaker 2: and a half volts, which would not be uncommon. Right, 677 00:33:27,760 --> 00:33:30,800 Speaker 2: start it up and just monitor it within time as 678 00:33:30,840 --> 00:33:32,840 Speaker 2: the vehicle runs, as it opens up the purge to 679 00:33:32,840 --> 00:33:35,720 Speaker 2: evacuate the canister and closes the vent, you're gonna see 680 00:33:35,800 --> 00:33:38,800 Speaker 2: FTP drawn into a vacuum state, and you'll see voltage 681 00:33:38,800 --> 00:33:42,760 Speaker 2: go lower. Okay, and and and then if it were 682 00:33:42,800 --> 00:33:46,280 Speaker 2: to close the purge close the vent, what would you 683 00:33:46,320 --> 00:33:50,160 Speaker 2: expect that voltage to do well? Would it go back up? 684 00:33:50,200 --> 00:33:53,760 Speaker 2: If it went back up, that means what it's losing vacuum. 685 00:33:53,800 --> 00:33:56,800 Speaker 2: That means it's got a leak. If the voltage, If 686 00:33:56,800 --> 00:33:59,720 Speaker 2: the voltage, if it's pulled into a vacuum state, suck 687 00:33:59,800 --> 00:34:03,760 Speaker 2: in and hold it right, it's in a vacuum state, 688 00:34:04,040 --> 00:34:07,960 Speaker 2: you would expect voltage to stay constant, right, Okay, So 689 00:34:08,760 --> 00:34:10,880 Speaker 2: if if we pull it into a vacuum state and 690 00:34:10,920 --> 00:34:14,359 Speaker 2: the FTP goes up, and the computers saying, wait, it's 691 00:34:14,400 --> 00:34:17,960 Speaker 2: supposed to stay at a constant voltage, I pulled it down, 692 00:34:18,000 --> 00:34:21,520 Speaker 2: what's going on? That's how it sets the leak. That graph, 693 00:34:21,920 --> 00:34:24,520 Speaker 2: this goes back to fifth grade geometry. That graph of 694 00:34:24,560 --> 00:34:27,560 Speaker 2: acceleration of how fast it goes up or how fast 695 00:34:27,640 --> 00:34:30,279 Speaker 2: it doesn't go up is an indicator of how big 696 00:34:30,360 --> 00:34:31,400 Speaker 2: or small the leak is. 697 00:34:31,760 --> 00:34:34,640 Speaker 3: They look at FTP. That's my point. 698 00:34:35,120 --> 00:34:38,800 Speaker 2: Now, when they did the tank, did the FTP get changed, 699 00:34:39,000 --> 00:34:42,040 Speaker 2: did they put all new rubber gramets right? Just what 700 00:34:42,200 --> 00:34:45,000 Speaker 2: exactly did they do and how did they do it? 701 00:34:45,440 --> 00:34:46,880 Speaker 2: So some things to go look at. 702 00:34:47,040 --> 00:34:47,239 Speaker 6: Right. 703 00:34:47,320 --> 00:34:49,680 Speaker 2: Also, if you get a scan tool, maybe it's got 704 00:34:49,680 --> 00:34:52,880 Speaker 2: easy interpretation of Mode six data. We can talk about 705 00:34:52,880 --> 00:34:54,960 Speaker 2: Mote six next when you call in. We can go 706 00:34:55,000 --> 00:34:57,400 Speaker 2: over that a little bit. But this is a pinhole. 707 00:34:57,600 --> 00:35:00,680 Speaker 2: We're looking for a pinhole, not necessarily something old or new. 708 00:35:00,680 --> 00:35:02,400 Speaker 2: It's just a problem. Go look at some of the 709 00:35:02,480 --> 00:35:04,080 Speaker 2: things we talked about and we can kind of pick 710 00:35:04,120 --> 00:35:06,440 Speaker 2: it up next time around. Stefan I enjoyed the call. 711 00:35:06,480 --> 00:35:08,919 Speaker 2: I'm running inde in the car doctor till the next time, 712 00:35:09,040 --> 00:35:12,520 Speaker 2: reminding you good mechanics aren't expensive, they're priceless. 713 00:35:12,800 --> 00:35:15,480 Speaker 5: See yu, Hey he's a car doctor. 714 00:35:16,400 --> 00:35:18,040 Speaker 3: Carr advice to write
