Jeremy, Welcome to the doctor, sir. 18 00:01:00,720 --> 00:01:04,240 Speaker 1: How can I help? Just too quickie here wondering what 19 00:01:04,360 --> 00:01:11,320 Speaker 1: your experiences in having to turn a machine new drums 20 00:01:12,040 --> 00:01:16,080 Speaker 1: right out of the box. He went install something and 21 00:01:16,200 --> 00:01:18,800 Speaker 1: I think you know I got Paulson having turned in 22 00:01:18,840 --> 00:01:22,640 Speaker 1: their brand new drums are just or drums and rotors 23 00:01:23,920 --> 00:01:26,959 Speaker 1: drums in particular. Yeah, you know, I've got to tell you, Jeremy, 24 00:01:27,000 --> 00:01:30,880 Speaker 1: the drum thing has been that way in the almost 25 00:01:30,959 --> 00:01:34,320 Speaker 1: fifty years. I'm repairing cars, and I'm not sure why. 26 00:01:34,560 --> 00:01:37,200 Speaker 1: And I agree it's and it's a valid question that 27 00:01:37,400 --> 00:01:39,920 Speaker 1: I still I will still machine a drum. I will. 28 00:01:40,000 --> 00:01:43,480 Speaker 1: I will start out maybe a three thousands cut, something 29 00:01:43,600 --> 00:01:46,240 Speaker 1: very light, and just to see what it looks like. 30 00:01:46,480 --> 00:01:49,640 Speaker 1: And you know, for the amount of drums that we 31 00:01:49,640 --> 00:01:52,080 Speaker 1: we still see because everything is getting before, we'll just 32 00:01:52,200 --> 00:01:55,720 Speaker 1: break um. You know it's yeah, you still see a 33 00:01:55,840 --> 00:02:01,000 Speaker 1: drummer too, you know, at around and I'm not I'm 34 00:02:01,040 --> 00:02:05,480 Speaker 1: not sure. Say again, I mean for a guy working 35 00:02:05,480 --> 00:02:10,040 Speaker 1: in the driveway, you know, oh yeah, absolutely. Um. I 36 00:02:10,040 --> 00:02:12,760 Speaker 1: I often wonder and I always thought about it, even 37 00:02:12,800 --> 00:02:16,040 Speaker 1: when I was a kid. I wonder how they stacked drums. 38 00:02:16,080 --> 00:02:18,440 Speaker 1: I wonder how they ship them, you know, do they 39 00:02:18,680 --> 00:02:20,440 Speaker 1: is it? Is it that there? You know, I imagine 40 00:02:20,440 --> 00:02:22,760 Speaker 1: them coming off the assembly line up the manufacturing and 41 00:02:22,760 --> 00:02:25,800 Speaker 1: they're they're putting a box and then um, you know, 42 00:02:25,840 --> 00:02:28,160 Speaker 1: they go down the conveyor belt. And I realized, I'm 43 00:02:28,200 --> 00:02:30,840 Speaker 1: just I'm guessing here, but I've always wondered this question. 44 00:02:31,120 --> 00:02:32,799 Speaker 1: Do they get boxed up at the end? Is there 45 00:02:32,800 --> 00:02:35,240 Speaker 1: a traffic jam and box after box hits box after 46 00:02:35,280 --> 00:02:37,600 Speaker 1: box hits the drum and kind of knocks it. You know, 47 00:02:37,720 --> 00:02:39,760 Speaker 1: it's think of the weight of a line of ten 48 00:02:39,840 --> 00:02:42,360 Speaker 1: or twelve or fifteen whatever drums. It is pushing against 49 00:02:42,360 --> 00:02:44,920 Speaker 1: each other. That last guy down at the bottoms got 50 00:02:44,919 --> 00:02:47,000 Speaker 1: a lot of weight on him. Is he slowly being 51 00:02:47,040 --> 00:02:50,519 Speaker 1: pushed out of shape? And the last guy to have 52 00:02:50,639 --> 00:02:53,400 Speaker 1: the bottoms one that ends up to turn the drum right, 53 00:02:53,480 --> 00:02:54,960 Speaker 1: And that's the one that you gotta You end up 54 00:02:54,960 --> 00:02:56,920 Speaker 1: turning the drum. And you know, how are they handled 55 00:02:57,320 --> 00:02:59,720 Speaker 1: from the time they come off the machine until they 56 00:02:59,720 --> 00:03:03,200 Speaker 1: get to you? And I always wonder that rotors not 57 00:03:03,280 --> 00:03:06,240 Speaker 1: so much. We very rarely have to cut new rotors 58 00:03:06,240 --> 00:03:11,760 Speaker 1: out of the box, you know, But yeah, anomaly, no 59 00:03:12,280 --> 00:03:14,959 Speaker 1: um drums are an issue. I'll tell you the other 60 00:03:15,000 --> 00:03:18,000 Speaker 1: thing that's kind of puzzling to me, and it's it's 61 00:03:18,040 --> 00:03:20,600 Speaker 1: not so much drums, but it's a it's a Subaru thing. 62 00:03:21,280 --> 00:03:25,040 Speaker 1: I've yet to do four wheel breaks on a Subaru. 63 00:03:25,360 --> 00:03:30,320 Speaker 1: Use anybody's break rotors other than Subaru and not have 64 00:03:30,560 --> 00:03:33,920 Speaker 1: to back cut the drum area where the parking break 65 00:03:34,040 --> 00:03:38,640 Speaker 1: shoe sits so that it doesn't rub the dust shield. 66 00:03:40,600 --> 00:03:44,920 Speaker 1: And I've had, dude, I have had conversations with engineers 67 00:03:44,920 --> 00:03:49,240 Speaker 1: at every break manufacturer that I can get my hands on. Um. 68 00:03:49,280 --> 00:03:51,280 Speaker 1: Every time I go to a trade show, they I 69 00:03:51,840 --> 00:03:53,760 Speaker 1: get into the booth and you know, get up in 70 00:03:53,800 --> 00:03:55,800 Speaker 1: their grill and say, hey, dude, you know, here's the deal, 71 00:03:55,840 --> 00:03:59,960 Speaker 1: here's what's going on. And you know, not that never happens. 72 00:04:00,000 --> 00:04:01,960 Speaker 1: We never get that complaint. Yeah, you know why nobody's 73 00:04:02,000 --> 00:04:04,440 Speaker 1: got the time because we just backcut the drum. We 74 00:04:04,440 --> 00:04:05,960 Speaker 1: we cut that, We cut a little, you know, and 75 00:04:06,000 --> 00:04:10,560 Speaker 1: we don't take much. We'll probably take thousands off and 76 00:04:10,680 --> 00:04:12,960 Speaker 1: the problem goes away. It's like they're just cast just 77 00:04:13,080 --> 00:04:16,120 Speaker 1: a little bit too much. At first, I thought the 78 00:04:16,360 --> 00:04:20,520 Speaker 1: backing plate was rusty, and it was you know, it 79 00:04:20,640 --> 00:04:23,719 Speaker 1: was an issue in that sense that but yeah, I've 80 00:04:23,720 --> 00:04:26,839 Speaker 1: had it with suber Us with no rust and everything 81 00:04:26,960 --> 00:04:30,800 Speaker 1: is high and dry as I like the O E. 82 00:04:30,920 --> 00:04:35,080 Speaker 1: M ones work fun. So you know, is it is 83 00:04:35,120 --> 00:04:40,040 Speaker 1: it the production tolerance? And you know it's it's nothing 84 00:04:40,200 --> 00:04:43,919 Speaker 1: is held to as good as tolerance. I I feel 85 00:04:44,080 --> 00:04:46,880 Speaker 1: in certain companies in the aftermarket as they are in 86 00:04:46,880 --> 00:04:50,520 Speaker 1: in the o E world, And yeah, it's it's it's 87 00:04:50,560 --> 00:04:52,600 Speaker 1: it's gonna be a real problem going forward. You wonder 88 00:04:52,600 --> 00:04:54,680 Speaker 1: how the after market companies are gonna keep up. And 89 00:04:54,680 --> 00:04:57,760 Speaker 1: and the crazy part is, I know in so many 90 00:04:57,800 --> 00:05:01,800 Speaker 1: cases where the after market companies are making the parts 91 00:05:01,800 --> 00:05:05,240 Speaker 1: for the OS and they're just spec it, right, they 92 00:05:05,240 --> 00:05:08,200 Speaker 1: can do it, they just choose not to. That's right, 93 00:05:08,240 --> 00:05:11,800 Speaker 1: because we end up having environment anyway. Right, And and 94 00:05:11,839 --> 00:05:15,479 Speaker 1: as as long as people continue to you know, purchase 95 00:05:15,560 --> 00:05:19,440 Speaker 1: these things, Um, it's it's just gonna be there. But yeah, 96 00:05:19,480 --> 00:05:22,200 Speaker 1: absolutely I feel your pain, I really do. Man, I'm sorry. 97 00:05:23,120 --> 00:05:24,680 Speaker 1: So you're very welcome. You have a good rest of 98 00:05:24,680 --> 00:05:29,360 Speaker 1: the day. Let's get over to Larry in Iowa eleven GMC. Yes, Larry, 99 00:05:29,400 --> 00:05:33,520 Speaker 1: how can I help? Hi? Ryan, Thanks for taking my call. Um. 100 00:05:33,560 --> 00:05:36,880 Speaker 1: I keep getting I have two different skiing tools. I 101 00:05:36,920 --> 00:05:39,839 Speaker 1: have a generic skiing tool and then I have also 102 00:05:39,960 --> 00:05:44,039 Speaker 1: have the Launch the X four thirty one, the Pro Mini. 103 00:05:44,160 --> 00:05:49,640 Speaker 1: Yeah yeah, yeah, yeah, I like it a lot. Um. Okay, 104 00:05:49,800 --> 00:05:54,720 Speaker 1: I keep getting a p O four four six um 105 00:05:54,800 --> 00:05:58,279 Speaker 1: and I've done the purgeing seal and I've also done 106 00:05:58,760 --> 00:06:02,240 Speaker 1: the service bay test with the scan tool. I mean 107 00:06:02,320 --> 00:06:05,960 Speaker 1: it keeps coming back. It seems correct on the Skian tool, 108 00:06:06,680 --> 00:06:11,760 Speaker 1: but it keeps coming back, so it passes it passes 109 00:06:11,839 --> 00:06:16,080 Speaker 1: the test. Yeah, but and you clear the code, it 110 00:06:16,120 --> 00:06:19,920 Speaker 1: passes the test, and you drive it and comes back 111 00:06:20,080 --> 00:06:21,400 Speaker 1: and then it comes back. And how long does it 112 00:06:21,400 --> 00:06:25,000 Speaker 1: take to come back? Um, It's usually like like if 113 00:06:25,040 --> 00:06:27,240 Speaker 1: I Philadelphia, I mean it will take a quarter of 114 00:06:27,240 --> 00:06:30,200 Speaker 1: a tank of fuel. You know, probably probably about three 115 00:06:30,279 --> 00:06:33,640 Speaker 1: or four days before it comes back. Okay, you've you've 116 00:06:33,680 --> 00:06:38,919 Speaker 1: replaced the canister vent or the purge. Um, I replaced 117 00:06:39,000 --> 00:06:44,960 Speaker 1: both and and the fuel tank pressure sensor. Okay, if 118 00:06:45,000 --> 00:06:48,240 Speaker 1: you if you because you know, we're we're we're looking 119 00:06:48,279 --> 00:06:52,960 Speaker 1: at and we're measuring in inches of water, and we're 120 00:06:53,000 --> 00:06:56,880 Speaker 1: we're looking to measure this down to you know, half 121 00:06:56,920 --> 00:06:59,440 Speaker 1: an inch of water, which is you know, six inches 122 00:06:59,440 --> 00:07:02,039 Speaker 1: of water is equal to one inch of vacuum. So 123 00:07:02,480 --> 00:07:07,320 Speaker 1: we're splitting the hair. All right. If you run the engine, 124 00:07:07,800 --> 00:07:11,760 Speaker 1: you know, looking at it a curve, vital and bring 125 00:07:11,840 --> 00:07:16,440 Speaker 1: up engine speed and open up the purge, does you 126 00:07:16,440 --> 00:07:19,080 Speaker 1: know if you command the purge, do you see fuel 127 00:07:19,080 --> 00:07:25,400 Speaker 1: tank pressure change? Yes, yes, both on UM like the 128 00:07:25,520 --> 00:07:30,240 Speaker 1: voltage and end the pressure. You don't have access to 129 00:07:30,240 --> 00:07:35,320 Speaker 1: a smoke machine, do you? I do not um UM. 130 00:07:35,360 --> 00:07:39,000 Speaker 1: I've also note like on freeze frame freeze frame data, 131 00:07:39,560 --> 00:07:43,080 Speaker 1: I've noticed that when it sets the code, it says 132 00:07:43,160 --> 00:07:49,160 Speaker 1: that the purge sillinoid is commanded at So it's doing 133 00:07:49,160 --> 00:07:51,440 Speaker 1: it cold when you start up. Actually it's doing it 134 00:07:51,520 --> 00:07:54,200 Speaker 1: during warm up. Where's where's where's cooling temperature? About a 135 00:07:54,240 --> 00:08:01,120 Speaker 1: hundred sixty degrees I believe it will UM. So it's 136 00:08:01,120 --> 00:08:03,640 Speaker 1: doing it. It's going to its purge event just before 137 00:08:03,680 --> 00:08:07,280 Speaker 1: the engine comes off open loop operation. That's probably an 138 00:08:07,320 --> 00:08:10,559 Speaker 1: open loop at that point. It's an eleven. But you've 139 00:08:10,760 --> 00:08:14,400 Speaker 1: pressed I see you've got you've got a leak somewhere 140 00:08:14,480 --> 00:08:18,600 Speaker 1: other than vent and purge. That's the problem. And here's 141 00:08:18,880 --> 00:08:21,160 Speaker 1: here's a case where you get you kind of need 142 00:08:21,200 --> 00:08:27,600 Speaker 1: a smoke machine. UM. I have seen a few canisters fail, 143 00:08:28,480 --> 00:08:31,040 Speaker 1: all right. I've actually seen some of the plays that 144 00:08:31,120 --> 00:08:34,800 Speaker 1: the seams on the charle curl canister UM split. But 145 00:08:34,880 --> 00:08:39,360 Speaker 1: they split a cold weather, UM, tough environment, and you know, 146 00:08:39,400 --> 00:08:41,600 Speaker 1: you you kind of want to see it under smoke, 147 00:08:41,679 --> 00:08:43,640 Speaker 1: but and you may not even see it with a 148 00:08:43,640 --> 00:08:45,880 Speaker 1: smoke machine, not to not not to blow smoke, no 149 00:08:45,960 --> 00:08:50,960 Speaker 1: pun intended, but um uh you know it's it's you're 150 00:08:51,000 --> 00:08:56,240 Speaker 1: you're you're looking for something that's smaller than the thickness 151 00:08:56,320 --> 00:08:59,880 Speaker 1: of a hair in terms of a leak. So it's 152 00:09:00,000 --> 00:09:02,280 Speaker 1: it's it's nothing you're not gonna see by visual eye. Yes, 153 00:09:02,320 --> 00:09:04,160 Speaker 1: you could go through and make sure all the lines 154 00:09:04,200 --> 00:09:09,560 Speaker 1: and fittings are are tight, but it's not seeing proper. 155 00:09:10,559 --> 00:09:12,920 Speaker 1: It's it's seeing a very small leak and it's it's 156 00:09:12,960 --> 00:09:15,960 Speaker 1: seeing it. Um when it goes into that purge event 157 00:09:16,240 --> 00:09:19,080 Speaker 1: is the best way I can describe it. So it's it's, 158 00:09:19,200 --> 00:09:23,440 Speaker 1: it's it's it's anything at that moment. So um, that's 159 00:09:23,520 --> 00:09:28,840 Speaker 1: that's that's kind of where you're at. Um so um. 160 00:09:28,880 --> 00:09:30,959 Speaker 1: I mean, I know I don't have a smoke machine, 161 00:09:31,240 --> 00:09:34,480 Speaker 1: but if so like but if I you know, if 162 00:09:34,520 --> 00:09:37,040 Speaker 1: I do get a smoke machine or whatever, or is 163 00:09:37,080 --> 00:09:39,240 Speaker 1: there any way I could like, you know, because if 164 00:09:39,280 --> 00:09:41,440 Speaker 1: I take the line off the back of you know, 165 00:09:41,559 --> 00:09:44,280 Speaker 1: the line that comes up to the back of the 166 00:09:44,320 --> 00:09:47,120 Speaker 1: purge valve, is that where you would hook up the 167 00:09:47,200 --> 00:09:50,520 Speaker 1: smoke machine or blow smoke through there. Well, if your 168 00:09:50,600 --> 00:09:55,040 Speaker 1: vehicle doesn't have a green service port. Okay, if it 169 00:09:55,080 --> 00:09:58,360 Speaker 1: doesn't have a green service port which has a straighter 170 00:09:58,440 --> 00:10:00,440 Speaker 1: valve in it, we take the straighter valve about because 171 00:10:00,440 --> 00:10:04,199 Speaker 1: we can flow more smoke. So you know, let's let's 172 00:10:04,280 --> 00:10:07,160 Speaker 1: just review it. Right. You've got an engine, You've got 173 00:10:07,200 --> 00:10:11,400 Speaker 1: a gas tank. You've got a vent line between the 174 00:10:11,520 --> 00:10:15,160 Speaker 1: gas tank and the engine collects fumes, right, or it 175 00:10:15,200 --> 00:10:17,480 Speaker 1: has the ability to collect fumes. Think of that as 176 00:10:17,480 --> 00:10:20,560 Speaker 1: the vacuum cleaner line. All right. When the computer says, hey, 177 00:10:20,600 --> 00:10:22,120 Speaker 1: I want to vent fumes out of the tank to 178 00:10:22,200 --> 00:10:25,160 Speaker 1: keep him from going elsewhere, it opens up the purge. 179 00:10:25,720 --> 00:10:29,000 Speaker 1: It will, under certain conditions open up the vent, so 180 00:10:29,120 --> 00:10:32,720 Speaker 1: fresh air is drawn through the vent through the canister, 181 00:10:33,640 --> 00:10:37,160 Speaker 1: all right. From the canister it's pulled into that fresh 182 00:10:37,200 --> 00:10:40,360 Speaker 1: air is pulled into the tank, and then the fumes 183 00:10:40,440 --> 00:10:42,160 Speaker 1: in the tank are, if you want to think of 184 00:10:42,200 --> 00:10:46,079 Speaker 1: it like this, pushed forward by the fresh air into 185 00:10:46,120 --> 00:10:48,840 Speaker 1: that line leading the vacuum cleaner line leading up to 186 00:10:48,880 --> 00:10:51,080 Speaker 1: the engine, and the purge allows the fumes to be 187 00:10:51,120 --> 00:10:53,920 Speaker 1: drawn into the engine to be burned. Right. They have 188 00:10:54,040 --> 00:10:56,360 Speaker 1: to they have to open the vent because in theory, 189 00:10:56,920 --> 00:10:59,720 Speaker 1: if they didn't open the vent and they sucked on it, 190 00:11:00,040 --> 00:11:03,000 Speaker 1: gonna pull the tank, you know, and collapse the tank. 191 00:11:03,080 --> 00:11:06,000 Speaker 1: So we don't want to do that, all right, So 192 00:11:06,360 --> 00:11:08,680 Speaker 1: you know, that's that's the basics of what and how 193 00:11:08,720 --> 00:11:12,040 Speaker 1: this works. So when you put smoke into that vacuum 194 00:11:12,040 --> 00:11:15,600 Speaker 1: cleaner line, you may have to, you know, follow the smoke, 195 00:11:16,040 --> 00:11:18,760 Speaker 1: put smoke in, go back to the vent. You know. 196 00:11:19,200 --> 00:11:20,880 Speaker 1: You know, with the engine off up in the air, 197 00:11:21,000 --> 00:11:24,200 Speaker 1: the vent valve is going to be open, right, So 198 00:11:24,240 --> 00:11:27,920 Speaker 1: you're gonna find out where the vent valve line is 199 00:11:28,200 --> 00:11:30,240 Speaker 1: simply by looking for smoke coming out of the end 200 00:11:30,280 --> 00:11:31,679 Speaker 1: of the line. It's gonna be a rubber tube is 201 00:11:31,760 --> 00:11:33,800 Speaker 1: usually they bury it in a frame rail or sometimes 202 00:11:33,840 --> 00:11:36,400 Speaker 1: it comes out direct. You've got to shut that vent. 203 00:11:36,480 --> 00:11:38,240 Speaker 1: Sometimes I have to take the vent, will stick my 204 00:11:38,280 --> 00:11:43,520 Speaker 1: finger in the hole, all right, and or something, and 205 00:11:43,559 --> 00:11:46,040 Speaker 1: then I look for leaks. The idea of the smoke 206 00:11:46,120 --> 00:11:49,920 Speaker 1: machine is you're flowing smoke at a proportionate value. There's 207 00:11:49,960 --> 00:11:52,240 Speaker 1: usually a flow meter or a little p in the line, 208 00:11:52,280 --> 00:11:55,120 Speaker 1: a little black p that floats, rises and falls, and 209 00:11:55,160 --> 00:11:57,240 Speaker 1: you're looking for that p to be down at the bottom. 210 00:11:58,559 --> 00:12:02,400 Speaker 1: All right, So is that does that make sense for you? Yeah, yeah, 211 00:12:03,160 --> 00:12:05,160 Speaker 1: all right, so you know what, stay right where here. 212 00:12:05,200 --> 00:12:06,319 Speaker 1: I got one more thing I want to add to it. 213 00:12:06,440 --> 00:12:08,000 Speaker 1: Let me pull over and take this pause. When I 214 00:12:08,000 --> 00:12:09,960 Speaker 1: come back, we'll finish up. I'm Ronandi in the car doctor. 215 00:12:10,040 --> 00:12:20,199 Speaker 1: Don't go anywhere, whether it's a little red Corvette or 216 00:12:20,800 --> 00:12:22,920 Speaker 1: you go. You've come to the right place to get 217 00:12:22,960 --> 00:12:25,280 Speaker 1: that car fixed. Ron and Nandy in the car doctor 218 00:12:25,600 --> 00:12:29,400 Speaker 1: eight five five five zero nine nine zero zero. Now 219 00:12:29,640 --> 00:12:34,040 Speaker 1: back to Ron, Larry and Iowa. You're still there, sir. 220 00:12:34,160 --> 00:12:36,440 Speaker 1: You know one last thing I wanted to mention regarding 221 00:12:36,480 --> 00:12:40,320 Speaker 1: this eleven GMC with the P zero four four six. Um, 222 00:12:40,440 --> 00:12:43,640 Speaker 1: have you seen GM bulletin fifteen oh six oh four 223 00:12:43,760 --> 00:12:48,440 Speaker 1: double oh two? U get your hands on that read 224 00:12:48,520 --> 00:12:51,880 Speaker 1: then all right now, now, part of the description there 225 00:12:52,000 --> 00:12:53,560 Speaker 1: is that the fuel tank, the fuel tank is not 226 00:12:53,600 --> 00:12:55,280 Speaker 1: hard to fill on this by chances it I didn't 227 00:12:55,280 --> 00:12:58,239 Speaker 1: think they ask that, okay. Um. Part of the description 228 00:12:58,400 --> 00:13:00,560 Speaker 1: is that the fuel tank might be hard to fill, 229 00:13:00,600 --> 00:13:03,480 Speaker 1: but it might have a P zero four four six, 230 00:13:03,520 --> 00:13:05,960 Speaker 1: P zero four fifty five. Uh, you know a bunch 231 00:13:05,960 --> 00:13:09,560 Speaker 1: of codes, and they talk about ways to verify do 232 00:13:09,640 --> 00:13:12,080 Speaker 1: you have because they've come out with a redesigned vent 233 00:13:12,200 --> 00:13:15,560 Speaker 1: valve also for some of these vehicles. So it's just 234 00:13:15,760 --> 00:13:18,400 Speaker 1: you know, for knowledge's sake, you know, research is such 235 00:13:18,400 --> 00:13:20,640 Speaker 1: a big part of the business today that um, it 236 00:13:20,640 --> 00:13:22,160 Speaker 1: wouldn't order to get your hands on and read that 237 00:13:22,200 --> 00:13:24,920 Speaker 1: bolted and and and see what that tells you to um, 238 00:13:24,960 --> 00:13:27,480 Speaker 1: if you can't. If you do find a smoke machine, 239 00:13:27,480 --> 00:13:29,480 Speaker 1: don't get smoke happy with it. That's the other thing 240 00:13:29,480 --> 00:13:32,200 Speaker 1: I wanted to mention, um well, and the reason is 241 00:13:32,240 --> 00:13:34,679 Speaker 1: they say that over a short period of time, they 242 00:13:34,679 --> 00:13:37,920 Speaker 1: don't want us to smoke a vehicle more than twice 243 00:13:38,640 --> 00:13:42,040 Speaker 1: in any given set time frame, simply because smoke is 244 00:13:42,080 --> 00:13:45,480 Speaker 1: a hydrocarbon based substance. What does the chart called canister do. 245 00:13:45,679 --> 00:13:49,200 Speaker 1: It absorbs hydrocarbon based fumes, right, so you can actually 246 00:13:49,240 --> 00:13:51,719 Speaker 1: you can actually damage the canister by putting smoke through 247 00:13:51,720 --> 00:13:54,640 Speaker 1: the system too many times into short period with with 248 00:13:54,640 --> 00:13:58,440 Speaker 1: with not enough, you know, purche cycles so um so 249 00:13:58,520 --> 00:14:00,280 Speaker 1: much so to the point I'll just point this out 250 00:14:00,280 --> 00:14:02,640 Speaker 1: real quick, accompanied by the name of a T S 251 00:14:02,679 --> 00:14:05,600 Speaker 1: Automotive Test Solutions Bernie Thompson out and I think it's 252 00:14:05,640 --> 00:14:09,560 Speaker 1: Colorado or yeah, Colorado and New Mexico, I forget, but Um, 253 00:14:09,600 --> 00:14:11,840 Speaker 1: he's got some interesting reads if you want to Google 254 00:14:11,880 --> 00:14:15,160 Speaker 1: search that where he's come out with a machine that 255 00:14:15,360 --> 00:14:21,040 Speaker 1: uses carbon dioxide and foam for leak detecting. Um. It 256 00:14:21,120 --> 00:14:22,600 Speaker 1: kind of a neat idea. We actually have the kit 257 00:14:22,680 --> 00:14:25,520 Speaker 1: in the shop and we've used it, um more than 258 00:14:25,560 --> 00:14:27,320 Speaker 1: a few times and it works quite well. It's an 259 00:14:27,360 --> 00:14:29,800 Speaker 1: alternative to smoke and sometimes we use it on air 260 00:14:29,840 --> 00:14:32,080 Speaker 1: conditioning systems and and other things that we're trying to 261 00:14:32,120 --> 00:14:34,600 Speaker 1: find leaks for. So you may want to look at 262 00:14:34,640 --> 00:14:38,560 Speaker 1: that too, all right, kiddo, All right, um, so, UM, 263 00:14:38,800 --> 00:14:42,960 Speaker 1: the purge and seal test, what is the correct amount 264 00:14:43,080 --> 00:14:47,640 Speaker 1: of decay when I do that? Well, the the tool 265 00:14:47,760 --> 00:14:50,520 Speaker 1: is going to tell you you should literally see you know, 266 00:14:50,520 --> 00:14:52,440 Speaker 1: when you do the purge and seal, if you're closing 267 00:14:52,480 --> 00:14:55,480 Speaker 1: the purge and the seal, actually you're closing the vent 268 00:14:56,120 --> 00:14:59,200 Speaker 1: leaving the purge open. The engine runs, it's looking to 269 00:14:59,240 --> 00:15:02,280 Speaker 1: pull vacu him in the tank. Fuel tank pressure centered 270 00:15:02,320 --> 00:15:04,760 Speaker 1: down to a certain state of vacuum over a set 271 00:15:04,800 --> 00:15:07,840 Speaker 1: time period, and then it then it caps the purge 272 00:15:08,200 --> 00:15:11,520 Speaker 1: and it looks to see does it rise If fuel 273 00:15:11,560 --> 00:15:15,920 Speaker 1: tank pressure rises too quick, that's when it fails. That's 274 00:15:15,920 --> 00:15:18,880 Speaker 1: a purge and seal. So in theory, it's supposed to 275 00:15:18,920 --> 00:15:20,720 Speaker 1: pull it down to whatever the number is, whatever it 276 00:15:20,720 --> 00:15:22,920 Speaker 1: wants it to be for that vehicle, and then it's 277 00:15:22,920 --> 00:15:27,240 Speaker 1: got to hold, all right, So well it should hold 278 00:15:27,640 --> 00:15:29,720 Speaker 1: if it doesn't. If it doesn't hold, then it sounds 279 00:15:29,720 --> 00:15:32,160 Speaker 1: like we've got a leak. Remember it's a purge and seal. 280 00:15:33,000 --> 00:15:36,160 Speaker 1: All right, it's a it's a and then hold your 281 00:15:36,160 --> 00:15:41,480 Speaker 1: broof that kind of thing. Alright, kidd alright, you're very welcome. 282 00:15:41,520 --> 00:15:43,320 Speaker 1: You take good care. Let's get over and talk to 283 00:15:43,400 --> 00:15:46,240 Speaker 1: Jeff in Minnesota. Look at this. It must be Camra 284 00:15:46,440 --> 00:15:49,000 Speaker 1: day here in the car. Doctor Jeff. How are you today, sir? 285 00:15:49,040 --> 00:15:51,200 Speaker 1: What's going on? Not a bad one? Good for you, 286 00:15:51,440 --> 00:15:54,440 Speaker 1: Thanks for having me on. This isn't so much of 287 00:15:54,480 --> 00:15:56,960 Speaker 1: a question as it is that I found something off 288 00:15:57,040 --> 00:15:59,240 Speaker 1: the hard way and I thought it would be good 289 00:15:59,280 --> 00:16:02,840 Speaker 1: to share it with so they don't same mistake. Now. 290 00:16:02,880 --> 00:16:04,920 Speaker 1: The last time I talked to you was almost a 291 00:16:05,000 --> 00:16:10,320 Speaker 1: year ago about a Chevrolet truck kunds. It's steered too 292 00:16:10,360 --> 00:16:13,760 Speaker 1: easy and uh it was one of those deals where 293 00:16:13,920 --> 00:16:17,280 Speaker 1: you couldn't It was a center on the para steering pump. 294 00:16:17,320 --> 00:16:20,720 Speaker 1: Reservoir that ended up being and you can't buy that part. 295 00:16:21,400 --> 00:16:24,240 Speaker 1: So I did. I did a salvage yard thing and 296 00:16:24,280 --> 00:16:26,920 Speaker 1: then and it took that one up just fine. Now 297 00:16:26,960 --> 00:16:30,720 Speaker 1: this canry that I ran into, same vintage. Um My 298 00:16:30,800 --> 00:16:32,880 Speaker 1: son and his wife drive it, and it's a hand 299 00:16:32,880 --> 00:16:35,040 Speaker 1: me down's got a ton of miles on it had 300 00:16:35,080 --> 00:16:37,360 Speaker 1: a tight spot in the steering. And what's the first 301 00:16:37,360 --> 00:16:40,720 Speaker 1: thing you think of, Well, it's the rack. Well I thought, well, 302 00:16:40,840 --> 00:16:46,720 Speaker 1: not so fast. So I disconnected the tyrods and um 303 00:16:46,720 --> 00:16:49,920 Speaker 1: turned the knuckles, you know, to make sure it wasn't 304 00:16:49,920 --> 00:16:53,600 Speaker 1: the ball joint or a bearing plate, and just assumed, 305 00:16:53,720 --> 00:16:56,640 Speaker 1: which gets us in trouble a lot, that it was 306 00:16:56,720 --> 00:16:59,280 Speaker 1: the wreck. So I put a reman rack in it, 307 00:16:59,640 --> 00:17:02,840 Speaker 1: went through all that malarkey, hooked it up and flushed 308 00:17:02,840 --> 00:17:05,199 Speaker 1: the fluid and everything and started it up, and you 309 00:17:05,240 --> 00:17:09,760 Speaker 1: know I still had a tight spot, same same problem, right, Yeah. Well, 310 00:17:09,760 --> 00:17:11,880 Speaker 1: I chased this thing around for a while and I thought, 311 00:17:11,920 --> 00:17:15,040 Speaker 1: what am I doing wrong here? And you know that 312 00:17:15,200 --> 00:17:18,720 Speaker 1: assuming thing. Um sometimes I rushed in there too quick, 313 00:17:18,720 --> 00:17:21,159 Speaker 1: and I just got to be the wreck. Make a 314 00:17:21,160 --> 00:17:24,359 Speaker 1: long story short, This car has two HU joints in 315 00:17:24,400 --> 00:17:27,240 Speaker 1: the steering shaft, one on the cabin side and one 316 00:17:27,280 --> 00:17:29,680 Speaker 1: on the fire engine side of the fire. The one 317 00:17:29,680 --> 00:17:33,560 Speaker 1: on the engine side was frozen exactly half one side 318 00:17:33,560 --> 00:17:36,439 Speaker 1: of it right, so when you turned that, it wouldn't 319 00:17:36,440 --> 00:17:38,280 Speaker 1: be tight all the time. It would be tight loose, 320 00:17:38,440 --> 00:17:43,560 Speaker 1: tight loose. The mistake I made was I didn't check. 321 00:17:43,760 --> 00:17:46,040 Speaker 1: I didn't turn that steering the lot the lot with 322 00:17:46,080 --> 00:17:48,480 Speaker 1: the engine off. Now, let me ask you this. Did 323 00:17:48,480 --> 00:17:53,719 Speaker 1: you did you replace that coupling or I did? Okay, 324 00:17:53,760 --> 00:17:56,600 Speaker 1: I have a solution. Tell you what, keep your radio one. 325 00:17:56,600 --> 00:17:58,520 Speaker 1: We're gonna pull over and take a pause. We're gonna 326 00:17:58,520 --> 00:17:59,960 Speaker 1: say a good body of but when we come back, 327 00:18:00,040 --> 00:18:01,919 Speaker 1: you'll hear the solution. I've got a solution for that 328 00:18:01,960 --> 00:18:05,439 Speaker 1: where sometimes that coupling doesn't have to be replaced. Um 329 00:18:05,480 --> 00:18:08,479 Speaker 1: and uh, it's just it's just a cheaper alternative. So um, 330 00:18:08,480 --> 00:18:10,520 Speaker 1: everybody stayed put on Ronald and the car doctor. We're 331 00:18:10,520 --> 00:18:33,159 Speaker 1: coming back right after this welcome back. Weren't any of 332 00:18:33,160 --> 00:18:35,760 Speaker 1: the car doctors. So for everyone out there listening, and 333 00:18:35,800 --> 00:18:38,520 Speaker 1: we were, we were just talking to um, I forget 334 00:18:38,520 --> 00:18:42,359 Speaker 1: his name with the camera it was it was camera 335 00:18:42,640 --> 00:18:46,439 Speaker 1: with Jeff from cameras from Minnesota about the steering coupling 336 00:18:46,760 --> 00:18:49,080 Speaker 1: that was getting tight. Um, you make up a batch 337 00:18:49,119 --> 00:18:51,719 Speaker 1: of ron soup, You get some you know, P B blaster, 338 00:18:52,280 --> 00:18:54,480 Speaker 1: and what you do is take the coupling off. Mark 339 00:18:54,640 --> 00:18:56,760 Speaker 1: the coupling when you take it off, because some of 340 00:18:56,800 --> 00:18:58,639 Speaker 1: these are not index and they can go on on 341 00:18:58,680 --> 00:19:01,359 Speaker 1: a multitude of positions. So I usually put a steak 342 00:19:01,440 --> 00:19:04,680 Speaker 1: mark or or a punch mark um on the ends 343 00:19:04,680 --> 00:19:07,560 Speaker 1: where they come apart, and and and mark it that way. 344 00:19:07,720 --> 00:19:09,720 Speaker 1: And what I'll do is lay it out on a 345 00:19:09,760 --> 00:19:13,240 Speaker 1: bench and rags underneath it on a shop towel, and 346 00:19:13,400 --> 00:19:16,000 Speaker 1: you know, a little p B blaster or some sort 347 00:19:16,000 --> 00:19:19,560 Speaker 1: of rust penetrant and allow it to soak, and you know, 348 00:19:19,560 --> 00:19:21,719 Speaker 1: flip it over, Let it soak, flip it over, let 349 00:19:21,760 --> 00:19:23,960 Speaker 1: it soak. You know, it's like a rotisserie. It might 350 00:19:23,960 --> 00:19:27,320 Speaker 1: take a day, all right. And then find yourself a 351 00:19:27,320 --> 00:19:30,840 Speaker 1: shop pan and fill it with a mixture just enough 352 00:19:30,840 --> 00:19:33,840 Speaker 1: to cover the top of the height with um uh 353 00:19:33,920 --> 00:19:35,800 Speaker 1: some p B. I usually inject some PB or some 354 00:19:35,880 --> 00:19:39,639 Speaker 1: kind of rust penetrant in there, and transmission fluid, transmission fluid. 355 00:19:39,680 --> 00:19:42,800 Speaker 1: Does it works, wonders, it really does? And soak that 356 00:19:42,880 --> 00:19:47,000 Speaker 1: coupling in this mixture, all right, there's no proportional mix here. 357 00:19:47,040 --> 00:19:48,760 Speaker 1: It's just just just a little at us and a 358 00:19:48,760 --> 00:19:50,880 Speaker 1: little of that and just soaking that. You can also 359 00:19:50,920 --> 00:19:52,600 Speaker 1: do the same thing with oil. Oil tends to be 360 00:19:52,640 --> 00:19:55,080 Speaker 1: a little bit harder in terms of its viscosity. It 361 00:19:55,119 --> 00:19:57,720 Speaker 1: doesn't flow as well. Transfluid really gets in there, and 362 00:19:57,760 --> 00:19:59,600 Speaker 1: you know, working around and work the joint and you'll 363 00:19:59,600 --> 00:20:01,760 Speaker 1: find in time, in a lot of cases, it will 364 00:20:01,800 --> 00:20:04,600 Speaker 1: free that coupling up. Now it's lubricated. Now put it 365 00:20:04,600 --> 00:20:07,679 Speaker 1: back in the car as long as there's nowhere. You know, 366 00:20:07,720 --> 00:20:10,600 Speaker 1: we've done this many times because that coupling. I've had 367 00:20:10,640 --> 00:20:14,480 Speaker 1: some of those couplings from Toyota eleven bucks. They're not cheap, 368 00:20:15,040 --> 00:20:16,960 Speaker 1: and um, you know, it's just a it's just a 369 00:20:17,040 --> 00:20:20,240 Speaker 1: cheaper alternative. Some of the early cameras or some of them, sorry, 370 00:20:20,240 --> 00:20:22,680 Speaker 1: some of the late nineties cameras. You have to replace 371 00:20:22,840 --> 00:20:25,639 Speaker 1: the column with the coupling. It's not a separate piece, 372 00:20:26,160 --> 00:20:28,600 Speaker 1: um in terms of how it's available. So in that case, 373 00:20:29,000 --> 00:20:30,879 Speaker 1: soak it in the car at PB and brush on 374 00:20:30,960 --> 00:20:33,639 Speaker 1: some trans fluid, flipping around like based in a turkey. 375 00:20:33,800 --> 00:20:36,240 Speaker 1: Very appropriate this time year, and um, you know that 376 00:20:36,240 --> 00:20:37,679 Speaker 1: will work too, So just a little bit of a 377 00:20:37,680 --> 00:20:40,240 Speaker 1: cost savings factor because some of the stuff's out of control. 378 00:20:40,440 --> 00:20:43,720 Speaker 1: James and Iowa oh one Chevy Malibu Surgeon highway speed. 379 00:20:43,720 --> 00:20:46,520 Speaker 1: How can I help you today, sir? What's going on? Well, sir, 380 00:20:46,840 --> 00:20:48,680 Speaker 1: it's a pleasure to talk to you. I'm a long 381 00:20:48,720 --> 00:20:54,320 Speaker 1: time listener. Uh. This car's got like two miles on it. 382 00:20:54,880 --> 00:20:59,960 Speaker 1: Chevy three one just broken in. Yeah, well absolutely, yeah, 383 00:21:00,080 --> 00:21:05,680 Speaker 1: so I buy them that way so, uh you can 384 00:21:05,720 --> 00:21:09,280 Speaker 1: feel it just a little bit at on the flat land, 385 00:21:09,359 --> 00:21:12,240 Speaker 1: but when you get going up the hill, it's a 386 00:21:12,400 --> 00:21:17,480 Speaker 1: it's a noticeable surge and it seems like if if 387 00:21:17,480 --> 00:21:20,640 Speaker 1: I dropped it. How to overdrive down the third gear 388 00:21:20,720 --> 00:21:22,720 Speaker 1: where I get t R P M S up, it 389 00:21:22,800 --> 00:21:27,600 Speaker 1: goes away. It's better, right, Yeah? So do you have 390 00:21:27,600 --> 00:21:31,399 Speaker 1: a scan tool? I do? Um? Have you looked at 391 00:21:31,440 --> 00:21:36,560 Speaker 1: fuel trims when this is happening? I have not? Do you? Um? 392 00:21:36,560 --> 00:21:40,440 Speaker 1: No insult intended. Do you understand the concept of fuel trim? Well, 393 00:21:40,640 --> 00:21:43,600 Speaker 1: you might want to remind me. It used to be 394 00:21:43,640 --> 00:21:46,840 Speaker 1: a mechanic, but it's been quite about quite a few years. 395 00:21:47,040 --> 00:21:50,600 Speaker 1: Did did you do um? Uh? Did you take geometry 396 00:21:50,600 --> 00:21:55,280 Speaker 1: in high school? Absolutely? And algebra. And remember when they 397 00:21:55,320 --> 00:21:58,679 Speaker 1: introduced us to those that that number chart where it 398 00:21:58,720 --> 00:22:01,040 Speaker 1: was zero in the middle, and it was plus one 399 00:22:01,040 --> 00:22:03,000 Speaker 1: and minus one and plus two and minus two and 400 00:22:03,040 --> 00:22:06,520 Speaker 1: all that, and and you said, and you said, gee, 401 00:22:06,520 --> 00:22:08,880 Speaker 1: where am I going to use that? Here's here's where 402 00:22:08,880 --> 00:22:11,280 Speaker 1: your here's where you're gonna use it. All right. So 403 00:22:11,680 --> 00:22:15,840 Speaker 1: zero is a balanced fuel mixture, all right. Zero is 404 00:22:16,720 --> 00:22:19,119 Speaker 1: you know, fourteen point seven to one air fuel mixture. 405 00:22:19,359 --> 00:22:22,399 Speaker 1: All right. So if we look at fuel trim on 406 00:22:22,400 --> 00:22:26,360 Speaker 1: a scan tool, um, typical short term fuel trim? What'd 407 00:22:26,400 --> 00:22:30,840 Speaker 1: you have for breakfast this morning? Uh? Nothing? Okay, so 408 00:22:30,920 --> 00:22:33,240 Speaker 1: that's your that's your short term. Your memory is you 409 00:22:33,320 --> 00:22:36,240 Speaker 1: had nothing for breakfast. You're zero? All right, So there's 410 00:22:36,320 --> 00:22:39,320 Speaker 1: zero fuel trim. That's right now this moment. What do 411 00:22:39,359 --> 00:22:41,760 Speaker 1: you have for dinner two weeks ago? You don't remember? 412 00:22:41,800 --> 00:22:45,879 Speaker 1: But the point is that's history. Okay. Long term is history. 413 00:22:46,160 --> 00:22:50,240 Speaker 1: Short term is now short term drives long term. Alright. 414 00:22:50,440 --> 00:22:53,320 Speaker 1: You're gonna see two numbers. You actually see four. You'll 415 00:22:53,320 --> 00:22:56,480 Speaker 1: see short term bank, one short term bank to long 416 00:22:56,600 --> 00:23:00,040 Speaker 1: term bank. One long term bank too, all right, you 417 00:23:00,040 --> 00:23:03,960 Speaker 1: want to look at both. Okay, you'll probably see because 418 00:23:03,960 --> 00:23:06,560 Speaker 1: this is this sounds like a lean surge, and this 419 00:23:06,600 --> 00:23:09,400 Speaker 1: will prove whether it is or not. If If if 420 00:23:09,480 --> 00:23:13,480 Speaker 1: long term fuel trim is somewhere around to three and 421 00:23:13,560 --> 00:23:17,760 Speaker 1: short term fuel trim is six eight percent, this is 422 00:23:17,800 --> 00:23:20,840 Speaker 1: not a fuel trim issue that sounds reasonable to me 423 00:23:20,880 --> 00:23:22,679 Speaker 1: on a car with two or twenty thousand miles on 424 00:23:22,760 --> 00:23:25,840 Speaker 1: it for the age of this alright, If long term 425 00:23:25,880 --> 00:23:28,919 Speaker 1: fuel trim is up in the fifteen eighteen percentile and 426 00:23:29,040 --> 00:23:32,800 Speaker 1: short term is ten twelve fiftcent it's climbing. This car 427 00:23:32,840 --> 00:23:35,880 Speaker 1: has got a vacuum leak, all right, And and it's 428 00:23:35,920 --> 00:23:38,600 Speaker 1: back to those you know, those those numbers in algebra 429 00:23:38,680 --> 00:23:42,280 Speaker 1: class zero plus one plus two. The plus means it's 430 00:23:42,359 --> 00:23:47,000 Speaker 1: adding fuel. It's trying to compensate for a lean running condition. Uh, 431 00:23:47,040 --> 00:23:50,800 Speaker 1: it's it's it's off it's base computer setting of it 432 00:23:50,880 --> 00:23:54,040 Speaker 1: expects to see this much air volume or this much 433 00:23:54,440 --> 00:23:58,280 Speaker 1: um oxygen sensor content based on the sensor input that 434 00:23:58,320 --> 00:24:00,800 Speaker 1: type of thing, all right, it's looking mass airflow and 435 00:24:00,840 --> 00:24:03,280 Speaker 1: O two censor and it's comparing and deciding what it 436 00:24:03,280 --> 00:24:07,000 Speaker 1: should be based off its programming. But if you see 437 00:24:07,080 --> 00:24:10,720 Speaker 1: higher than normal numbers, it's off base. That means where's 438 00:24:10,720 --> 00:24:14,399 Speaker 1: it coming from. Maybe we've got a bad mass airflow sensor. 439 00:24:14,480 --> 00:24:17,199 Speaker 1: Maybe we've got a bad mass airflow duct. Some of 440 00:24:17,240 --> 00:24:19,320 Speaker 1: the things we can look at visually, but we've got 441 00:24:19,320 --> 00:24:21,320 Speaker 1: to think about looking for a vacuum week. So let 442 00:24:21,320 --> 00:24:24,000 Speaker 1: me tell you this procedure real quick before we run 443 00:24:24,040 --> 00:24:26,640 Speaker 1: out of time. Um. If you do have a scan 444 00:24:26,680 --> 00:24:29,480 Speaker 1: tool and you think it's a vacuum leek, pop the 445 00:24:29,520 --> 00:24:31,720 Speaker 1: PCV valve out of the out of the valve cover, 446 00:24:32,320 --> 00:24:34,040 Speaker 1: seal it with a piece of seal that port with 447 00:24:34,080 --> 00:24:36,480 Speaker 1: a piece of duct tape so it's sealed, and then 448 00:24:37,000 --> 00:24:40,560 Speaker 1: seal the PCD port where it goes into the engine. 449 00:24:41,359 --> 00:24:45,480 Speaker 1: Pulled the dipstick tube started up. If you've got a 450 00:24:45,600 --> 00:24:49,440 Speaker 1: higher vacuum reading running and as you crease engines, beat 451 00:24:49,560 --> 00:24:53,159 Speaker 1: vacuum goes up, you've got a vacuum week somewhere. You're 452 00:24:53,200 --> 00:24:57,159 Speaker 1: pulling it probably my guess is from under the intake planum, 453 00:24:57,200 --> 00:25:01,000 Speaker 1: and you'll you won't see it all right. Um. Now 454 00:25:01,240 --> 00:25:03,320 Speaker 1: you could also try this if you want to take 455 00:25:03,320 --> 00:25:05,440 Speaker 1: a little bit of water and an atomizer bottle or 456 00:25:05,440 --> 00:25:08,159 Speaker 1: a stream of water and start shooting around the intake 457 00:25:08,200 --> 00:25:11,640 Speaker 1: ports and see if anything there changes engine speed. All right, 458 00:25:11,880 --> 00:25:14,040 Speaker 1: I'm not as accurate, not as fast. A bottle of 459 00:25:14,080 --> 00:25:16,080 Speaker 1: propane with a pinched off brake line in the end 460 00:25:16,080 --> 00:25:18,639 Speaker 1: of it, with the propane and Richmond tool I always 461 00:25:18,680 --> 00:25:21,119 Speaker 1: talk about does help. This is where you're looking for. 462 00:25:21,160 --> 00:25:24,080 Speaker 1: This also all the time. If you're shooting propane into it, 463 00:25:24,400 --> 00:25:27,040 Speaker 1: you can also take a look at and be aware 464 00:25:27,119 --> 00:25:29,359 Speaker 1: that you know, um, you can look at it on 465 00:25:29,359 --> 00:25:32,320 Speaker 1: a scan tool. If you shoot some propane into the engine, 466 00:25:32,480 --> 00:25:35,840 Speaker 1: you can watch the scan tool fuel trim change. That's 467 00:25:36,040 --> 00:25:40,080 Speaker 1: you know, use the tools you've got. You don't think 468 00:25:40,119 --> 00:25:43,399 Speaker 1: it might be maybe a chlo pack breaking down on 469 00:25:43,560 --> 00:25:46,560 Speaker 1: me or why why would you think that prove prove 470 00:25:46,640 --> 00:25:53,280 Speaker 1: your theory to me? Brother? Uh in La, it's getting 471 00:25:53,320 --> 00:25:56,960 Speaker 1: colder and and and I know those those col packs 472 00:25:57,000 --> 00:25:59,120 Speaker 1: do break down. They do. Why aren't you say, why 473 00:25:59,119 --> 00:26:03,959 Speaker 1: aren't you getting a misfar? Are full? Well? That's very true. Okay, 474 00:26:04,200 --> 00:26:06,560 Speaker 1: does your scan tool? Does your scan tool have Mode 475 00:26:06,560 --> 00:26:09,800 Speaker 1: six data in it? It does not. It's it's one 476 00:26:09,800 --> 00:26:13,560 Speaker 1: of the cheaper version. So and listen, you know what 477 00:26:13,760 --> 00:26:17,320 Speaker 1: you call a surge maybe a misfire, but I'm interpreting 478 00:26:17,320 --> 00:26:21,560 Speaker 1: it as a surge valid points. But I'll tell you what, 479 00:26:22,440 --> 00:26:25,920 Speaker 1: UM looking at fuel trim doing what I said. If 480 00:26:25,920 --> 00:26:31,399 Speaker 1: fuel trim looks normal, James absolutely spot on. Like you know, 481 00:26:31,480 --> 00:26:34,160 Speaker 1: like I said, the short term is you know three 482 00:26:34,240 --> 00:26:37,080 Speaker 1: or four or five. Long term is to three. It's 483 00:26:37,119 --> 00:26:39,399 Speaker 1: it's nothing out of the ordinary. Guess what it's not 484 00:26:39,440 --> 00:26:42,560 Speaker 1: a vacuum leak. Then we can talk about something else. 485 00:26:43,760 --> 00:26:48,320 Speaker 1: Sometimes sometimes diagnosing instead of looking for what's bad, prove 486 00:26:48,400 --> 00:26:53,399 Speaker 1: what's proof, Prove what's right, and eliminator. You know, and 487 00:26:53,440 --> 00:26:55,600 Speaker 1: I do understand that. You know, when when you go 488 00:26:55,680 --> 00:26:57,640 Speaker 1: to the doctor, what's the first thing they always do? 489 00:26:57,880 --> 00:27:02,840 Speaker 1: Heart rate? Blood pressure? Um, you know, maybe an X ray, fluids, 490 00:27:02,880 --> 00:27:05,919 Speaker 1: blood right, They look at everything. You don't go in 491 00:27:05,920 --> 00:27:07,720 Speaker 1: there and say, you know, doc, my stomach krts. He 492 00:27:07,760 --> 00:27:10,240 Speaker 1: doesn't cut your stomach out right away, right. He looks 493 00:27:10,240 --> 00:27:15,480 Speaker 1: at everything, Um, same thing, different model does the uh. 494 00:27:17,520 --> 00:27:19,040 Speaker 1: Once in a while, I get a code for the 495 00:27:19,080 --> 00:27:23,040 Speaker 1: downstream O two. Okay, I don't think that would cause 496 00:27:23,080 --> 00:27:24,879 Speaker 1: that with that, well, it depends how you're getting a 497 00:27:24,920 --> 00:27:27,440 Speaker 1: performance fault, the heat or circuit fault. What do you 498 00:27:27,440 --> 00:27:29,520 Speaker 1: you know? Which which code do you get? It's it's 499 00:27:29,520 --> 00:27:34,359 Speaker 1: a it's a performance fault. You know what downstream downstream 500 00:27:34,400 --> 00:27:37,199 Speaker 1: OH two does on some vehicles, and I believe this 501 00:27:37,240 --> 00:27:41,720 Speaker 1: one too. Um, it does have an influence on fuel strategy, 502 00:27:42,359 --> 00:27:47,600 Speaker 1: so it could Does the vehicle have an exhaust leak? Well, 503 00:27:48,040 --> 00:27:50,040 Speaker 1: the mufflers bad on it? All right, yeah, but that's 504 00:27:50,080 --> 00:27:52,280 Speaker 1: downstream of the O two. Unless we're getting a reversion issue, 505 00:27:52,280 --> 00:27:54,399 Speaker 1: which I don't think you are. It's too far back. 506 00:27:54,880 --> 00:27:58,200 Speaker 1: So listen, diagnosis begins with the first step. First step, 507 00:27:58,440 --> 00:28:02,080 Speaker 1: let's look at fuel trim and let's see what's going on. So, um, 508 00:28:02,119 --> 00:28:05,240 Speaker 1: you know, we'll kind of go from there. All right, kiddo, good, 509 00:28:05,320 --> 00:28:07,720 Speaker 1: all right, all right, thanks James.

Richard Vermont eight six s tensity Blazer, 523 00:28:48,400 --> 00:28:51,400 Speaker 1: Good sir, what's going on? Oh? I got n S 524 00:28:51,400 --> 00:29:00,880 Speaker 1: ten Blazer uh V six two point eight. Uh well, 525 00:29:00,920 --> 00:29:02,600 Speaker 1: this one I got. I got a couple of them. 526 00:29:02,760 --> 00:29:06,680 Speaker 1: Uh uh. It's an automatic and the problem is I 527 00:29:06,680 --> 00:29:09,400 Speaker 1: put a new gas tank in it, new new pumping 528 00:29:09,480 --> 00:29:14,160 Speaker 1: it um and it worked for a while and then 529 00:29:14,160 --> 00:29:17,880 Speaker 1: it shut down. And I was told that the three 530 00:29:17,920 --> 00:29:20,560 Speaker 1: modules on the left hand side of the firewall, some 531 00:29:20,720 --> 00:29:24,680 Speaker 1: have to some have one, some have three. I got 532 00:29:24,720 --> 00:29:28,360 Speaker 1: a couple of them. I I find a whole car 533 00:29:28,400 --> 00:29:30,160 Speaker 1: if I can find them. So let me let me 534 00:29:30,200 --> 00:29:31,680 Speaker 1: ask you this, rich because we don't have a lot 535 00:29:31,760 --> 00:29:34,640 Speaker 1: of time. So the car doesn't start right. The car 536 00:29:34,680 --> 00:29:37,880 Speaker 1: doesn't run right now, not now, not after I did 537 00:29:37,920 --> 00:29:40,880 Speaker 1: all that, it was running fine. So here hear me out. 538 00:29:41,160 --> 00:29:44,080 Speaker 1: So what is it missing? Does it have spark? Does 539 00:29:44,120 --> 00:29:47,479 Speaker 1: it have fuel pressure? Does it crank normal? Put your 540 00:29:47,480 --> 00:29:50,520 Speaker 1: hand on the gas tank and if it's running, it 541 00:29:51,360 --> 00:29:55,600 Speaker 1: wants to turnover, wants to turnover, and uh, that doesn't 542 00:29:55,640 --> 00:30:00,160 Speaker 1: go dead. They're spark. But I think one of those modules, 543 00:30:00,000 --> 00:30:02,560 Speaker 1: it's something to do it with the gas type. Well, 544 00:30:02,720 --> 00:30:09,200 Speaker 1: do you have fuel pressure? Yes, so you have fuel pressure? Okay, no, no, No, 545 00:30:09,360 --> 00:30:11,360 Speaker 1: the pumps not working because you can hear it if 546 00:30:11,400 --> 00:30:13,480 Speaker 1: you put your hand on a gas type and underneath 547 00:30:13,480 --> 00:30:15,680 Speaker 1: the ask you can hear it. You can feel it 548 00:30:15,960 --> 00:30:20,120 Speaker 1: if it's working. Okay, So the fuel pumps not turning on? 549 00:30:21,000 --> 00:30:24,760 Speaker 1: Right right, right, there's something like that. Okay, Well we 550 00:30:25,120 --> 00:30:29,240 Speaker 1: have a time time time time, brother, Um, it can't 551 00:30:29,240 --> 00:30:31,880 Speaker 1: be something like that. Either fuel pumps working or it's not. 552 00:30:32,040 --> 00:30:34,280 Speaker 1: So then the next question is, and I think what 553 00:30:34,360 --> 00:30:36,800 Speaker 1: you're talking about when you're saying modules, I think you're 554 00:30:36,840 --> 00:30:41,320 Speaker 1: talking about relays up on the passenger side of the firewall, 555 00:30:41,320 --> 00:30:44,800 Speaker 1: because that's where the relay bank was. So do we 556 00:30:44,920 --> 00:30:47,320 Speaker 1: have you know, listen, this is this is basic. Let 557 00:30:47,360 --> 00:30:48,840 Speaker 1: me let me leave here because we're gonna run out 558 00:30:48,840 --> 00:30:51,400 Speaker 1: of time. Um, this is basic. Do we have spark? 559 00:30:51,560 --> 00:30:53,400 Speaker 1: If we have spark at a at a at a 560 00:30:53,440 --> 00:30:57,280 Speaker 1: plug wire, we've got spark. If we don't have fuel pressure, 561 00:30:57,520 --> 00:31:00,680 Speaker 1: then we've got a pump issue. Okay, let's go back 562 00:31:00,680 --> 00:31:04,719 Speaker 1: to the tank. Do we have power, power and ground 563 00:31:05,040 --> 00:31:09,760 Speaker 1: at the connector for the fuel pump? Yes? Or no? Okay? Um, 564 00:31:10,000 --> 00:31:11,680 Speaker 1: if we have a scan tool and we plug in 565 00:31:11,720 --> 00:31:15,000 Speaker 1: a scan tool, can we read cranking our PM while 566 00:31:15,040 --> 00:31:19,600 Speaker 1: you're trying to start it. If we can, then we 567 00:31:19,760 --> 00:31:22,360 Speaker 1: can be pretty confident that we're getting proper signal out 568 00:31:22,360 --> 00:31:26,640 Speaker 1: of the ignition module to the PCM. It sees crank 569 00:31:27,600 --> 00:31:31,240 Speaker 1: and it should be energizing, grounding the fuel pump relay 570 00:31:31,520 --> 00:31:34,920 Speaker 1: causing the truck to run. If we have power at 571 00:31:35,040 --> 00:31:38,320 Speaker 1: the fuel pump connector in the back, power and ground, 572 00:31:38,800 --> 00:31:42,880 Speaker 1: right electrical motor. If we have power and ground and 573 00:31:42,960 --> 00:31:45,480 Speaker 1: the pump doesn't run, why can't we just have a 574 00:31:45,520 --> 00:31:49,680 Speaker 1: bad new pump. So let's, you know, let's get away 575 00:31:49,680 --> 00:31:52,160 Speaker 1: from here. Say let's get away from what a coulda shoulda, 576 00:31:52,600 --> 00:31:54,760 Speaker 1: and let's think about how this circuit works. I don't 577 00:31:54,760 --> 00:31:59,400 Speaker 1: care if it's a car, a motorcycle, a boat, or 578 00:31:59,800 --> 00:32:04,600 Speaker 1: a lawnmower, spark fuel mechanical. If it doesn't have fuel, 579 00:32:04,880 --> 00:32:07,520 Speaker 1: how does that fuel pump circuit work. You've got to 580 00:32:07,560 --> 00:32:10,640 Speaker 1: get a wiring diagram and I'm more than glad to 581 00:32:10,640 --> 00:32:12,720 Speaker 1: send you once. Send me an email Ron at Car 582 00:32:12,800 --> 00:32:16,280 Speaker 1: Doctor show dot com include the seventeen digit vin. I'm 583 00:32:16,320 --> 00:32:18,080 Speaker 1: sure I can come up with a wiring diagram for 584 00:32:18,200 --> 00:32:20,440 Speaker 1: this and take you through this before you just start 585 00:32:20,480 --> 00:32:23,240 Speaker 1: buying modules on the right side of the firewall. That 586 00:32:23,320 --> 00:32:28,560 Speaker 1: doesn't work. But just just think your thought process through, brother, Um. 587 00:32:28,760 --> 00:32:31,920 Speaker 1: Power at the fuel pump? Yes, no, yes? Uh? You 588 00:32:31,960 --> 00:32:34,000 Speaker 1: know do we have a bad pump just because you 589 00:32:34,040 --> 00:32:35,560 Speaker 1: put it in the truck. It was new when you 590 00:32:35,600 --> 00:32:38,760 Speaker 1: put it in new means, as we all know, never 591 00:32:38,800 --> 00:32:41,080 Speaker 1: ever worked. I'm running ending the Car Doctor back to 592 00:32:41,200 --> 00:32:45,320 Speaker 1: round it up right after this, Hey, Ron, any of 593 00:32:45,360 --> 00:32:48,440 Speaker 1: the Car Doctor um quick?

I get my beauty sleep 613 00:33:34,800 --> 00:33:37,560 Speaker 1: face made for radio. This could be rough, um, but anyway, 614 00:33:37,600 --> 00:33:40,000 Speaker 1: we're doing that next weekend and I'll miss Tom and Mikey. 615 00:33:40,040 --> 00:33:42,320 Speaker 1: They'll be back here at home base making it work 616 00:33:42,320 --> 00:33:44,479 Speaker 1: as they do their magic on that side of the glass. 617 00:33:44,480 --> 00:33:46,959 Speaker 1: So um, let's do it. Because quick piece of email. Hey, 618 00:33:47,000 --> 00:33:51,120 Speaker 1: ron Kadia, my wife has equinox. One family trip to 619 00:33:51,200 --> 00:33:53,720 Speaker 1: Yosemite this past summer. My wife says, hey, You're acy 620 00:33:53,800 --> 00:33:55,680 Speaker 1: doesn't work as well as mine. I know, I said, 621 00:33:55,680 --> 00:33:58,120 Speaker 1: but he catches up. This comes to us from Craig, 622 00:33:58,520 --> 00:34:00,720 Speaker 1: I've always had both cars dealers service. They don't trust 623 00:34:00,760 --> 00:34:02,440 Speaker 1: the quick oil changed places to do the right thing. 624 00:34:02,520 --> 00:34:05,160 Speaker 1: I understand that this fall I brought snow tires. Very 625 00:34:05,240 --> 00:34:07,640 Speaker 1: nice place, clean waiting room, polite, smile, greetings. So I 626 00:34:07,640 --> 00:34:09,319 Speaker 1: mentioned that the frost was taking too long in a 627 00:34:09,320 --> 00:34:12,279 Speaker 1: fan sound it's low, feeling foolish. But the owner asked me, 628 00:34:12,480 --> 00:34:14,560 Speaker 1: you know, after all this time and I've had the 629 00:34:14,600 --> 00:34:17,279 Speaker 1: car service on a regular basis, when I changed the 630 00:34:17,320 --> 00:34:21,000 Speaker 1: cabin filter, I said, I have one. All this time 631 00:34:21,040 --> 00:34:22,880 Speaker 1: at the dealer, they tried to sell me break jobs 632 00:34:22,880 --> 00:34:25,600 Speaker 1: that weren't needed, struts that weren't needed. Engine air filter 633 00:34:25,719 --> 00:34:27,920 Speaker 1: is not needed, but never checked the cabin air filter. 634 00:34:28,000 --> 00:34:30,040 Speaker 1: Oh well, makes a big difference. Now I have to 635 00:34:30,080 --> 00:34:31,759 Speaker 1: keep the fan at half position. And by the way, 636 00:34:31,800 --> 00:34:33,799 Speaker 1: I went out to Wicks Filters dot Com and I 637 00:34:33,880 --> 00:34:36,760 Speaker 1: purchased a Wicks filter, a Wix cabin air filter, using 638 00:34:36,800 --> 00:34:41,160 Speaker 1: their UM, using their cabin filtration system, their pure of technology, 639 00:34:41,160 --> 00:34:46,000 Speaker 1: and boy sure smells good inside my acadia. Craig, You know, Craig, 640 00:34:46,160 --> 00:34:49,200 Speaker 1: sometimes it's the simple things that make it work right. 641 00:34:49,280 --> 00:34:52,719 Speaker 1: It's we overlooked the obvious right and it's it's what 642 00:34:52,800 --> 00:34:55,080 Speaker 1: I always say, show me what's good, and I'll tell 643 00:34:55,080 --> 00:34:58,640 Speaker 1: you what's bad. And just diagnosed, diagnosed, diagnosed. It begins 644 00:34:58,680 --> 00:35:01,000 Speaker 1: at all levels. It's sometimes it starts with, Hey, I 645 00:35:01,040 --> 00:35:02,759 Speaker 1: gotta open the front door. I gotta put my foot 646 00:35:02,760 --> 00:35:04,600 Speaker 1: in my hand out and turn the knob. It's just 647 00:35:04,640 --> 00:35:07,359 Speaker 1: the way it works. I'm running Indian the car doctor boy, 648 00:35:07,400 --> 00:35:09,240 Speaker 1: It's been a great time being here this week. Until 649 00:35:09,280 --> 00:35:12,839 Speaker 1: the next time. Good mechanics aren't expensive, they're priceless. See 650 00:35:12,880 --> 00:35:12,920 Speaker 1: you
