2
00:00:06,800 --> 00:00:09,480
Speaker 2: I'm wondering why you want to buy something that's, you know,

3
00:00:09,640 --> 00:00:13,119
Speaker 2: a known problem, because my first question is you know

4
00:00:13,840 --> 00:00:15,400
Speaker 2: where the problems resolved.

5

00:00:20,280 --> 00:00:24,239
Speaker 2: You've got a misfire on cylinder one. That doesn't necessarily

7
00:00:24,360 --> 00:00:25,560
Speaker 2: mean it's just spark.

8

00:01:30,640 --> 00:01:35,200
Speaker 2: that's listening. Take everything you know about cars and move

31
00:01:35,240 --> 00:01:37,480
Speaker 2: it over to the side on a weekly basis, because

32
00:01:37,480 --> 00:01:42,000
Speaker 2: there's always something new to learn. Most of you, I hope,

33
00:01:42,760 --> 00:01:45,360
Speaker 2: think you have a great mechanic, and that's good. I'm

34
00:01:45,400 --> 00:01:48,640
Speaker 2: happy for you. I think having one you can trust,

35
00:01:49,040 --> 00:01:52,840
Speaker 2: having one that solves your problem is really an important

36
00:01:52,840 --> 00:01:55,640
Speaker 2: part of the ownership process. Hey, if you're gonna drive

37
00:01:55,640 --> 00:01:57,760
Speaker 2: a car, I don't care how new it is, Sooner

38
00:01:57,880 --> 00:02:01,800
Speaker 2: or later it's gonna break. But even that great mechanic

39
00:02:02,520 --> 00:02:08,400
Speaker 2: has its limits, and those limits are increasing every day

40
00:02:08,520 --> 00:02:12,920
Speaker 2: because of technology. Regardless of how good you think he is,

41
00:02:13,040 --> 00:02:16,880
Speaker 2: he or she is, sooner or later their tooling knowledge

42
00:02:16,880 --> 00:02:18,160
Speaker 2: and the car in front of him is going to

43
00:02:18,240 --> 00:02:21,280
Speaker 2: put them up against the wall. Welcome to the Repair

44
00:02:21,280 --> 00:02:25,880
Speaker 2: of the Week. Two thousand and six Accurate MDX SUV

45
00:02:26,000 --> 00:02:28,959
Speaker 2: version of an Accura came into Ari Automotive this week

46
00:02:29,320 --> 00:02:30,960
Speaker 2: and it was sort of a comeback. I have to

47
00:02:30,960 --> 00:02:32,840
Speaker 2: tell you I had just done a timing belt and

48
00:02:32,880 --> 00:02:36,160
Speaker 2: a throttle body cleaning two weeks prior, which is normal maintenance.

49
00:02:36,200 --> 00:02:38,240
Speaker 2: The car only had sixty five thousand miles on it,

50
00:02:38,280 --> 00:02:40,280
Speaker 2: but it was eight years old. It was time by time.

51
00:02:40,400 --> 00:02:44,360
Speaker 2: The timing belt was way overdue. What could go wrong?

52
00:02:44,880 --> 00:02:49,080
Speaker 2: And our story begins. Repairs were normal. The timing belt

53
00:02:49,120 --> 00:02:51,880
Speaker 2: was glazed but not broken. The tension or the hydraulic

54
00:02:51,919 --> 00:02:54,120
Speaker 2: tensioner was leaking. It had a well of oil in it,

55
00:02:54,360 --> 00:02:56,040
Speaker 2: and I was glad we were changing it because you

56
00:02:56,080 --> 00:02:58,480
Speaker 2: could see that clearly it was on the road to failure.

57
00:02:58,800 --> 00:03:02,680
Speaker 2: And the throttle body was filthy. It was dirty, dirty

58
00:03:02,680 --> 00:03:05,360
Speaker 2: throttle bodies. Throttle bodies are the part of the engine

59
00:03:05,400 --> 00:03:09,200
Speaker 2: where the air goes through. It's the air intake, and

60
00:03:09,480 --> 00:03:13,520
Speaker 2: they're interesting depending upon the manufacturer, just about all of

61
00:03:13,560 --> 00:03:17,160
Speaker 2: them require a reset. Think of the front door to

62
00:03:17,200 --> 00:03:20,320
Speaker 2: your house. You open and close it. This is open,

63
00:03:20,520 --> 00:03:23,760
Speaker 2: this is closed, this is open, this is closed. That

64
00:03:23,840 --> 00:03:27,800
Speaker 2: position never changes well on a throttle body because of

65
00:03:27,880 --> 00:03:29,960
Speaker 2: where it's located in the job that it has to

66
00:03:30,000 --> 00:03:33,440
Speaker 2: do a certain amount of dirt builds up around the

67
00:03:33,520 --> 00:03:37,520
Speaker 2: door gasket or the throttle plate to the housing. So

68
00:03:37,720 --> 00:03:39,520
Speaker 2: think of the front door to your house. If you

69
00:03:39,560 --> 00:03:42,520
Speaker 2: lived in the Mohave Desert and there was a sandstorm

70
00:03:42,560 --> 00:03:44,280
Speaker 2: and all the sand was blowing in the front door,

71
00:03:44,280 --> 00:03:47,240
Speaker 2: it would build up around the weather seal, and as

72
00:03:47,240 --> 00:03:49,120
Speaker 2: you went to close the door, it would bind and

73
00:03:49,880 --> 00:03:53,040
Speaker 2: stick and it wouldn't release properly, so you'd have to

74
00:03:53,040 --> 00:03:53,480
Speaker 2: clean it.

75
00:03:54,400 --> 00:03:54,560
Speaker 3: Well.

76
00:03:54,560 --> 00:03:56,440
Speaker 2: If you attach the computer to that front door and

77
00:03:56,480 --> 00:03:59,560
Speaker 2: you clean that gasket and you change the position of

78
00:03:59,560 --> 00:04:03,920
Speaker 2: the door from being closed at two degrees back to zero,

79
00:04:04,520 --> 00:04:07,160
Speaker 2: who was now closed at zero? Flush again? You got

80
00:04:07,200 --> 00:04:09,600
Speaker 2: to tell the computer where that position is. Hence the

81
00:04:09,720 --> 00:04:14,160
Speaker 2: rationale on why throttle body resets usually have to be

82
00:04:14,280 --> 00:04:18,400
Speaker 2: done now. It's important and even more so important on

83
00:04:18,440 --> 00:04:21,520
Speaker 2: a drive by wire car, and most vehicles on the

84
00:04:21,600 --> 00:04:23,960
Speaker 2: road today are matter of fact, I think all vehicles

85
00:04:23,960 --> 00:04:26,320
Speaker 2: being produced today, it's safe to say in the last

86
00:04:26,360 --> 00:04:28,520
Speaker 2: five years or drive by wire. I don't know of

87
00:04:28,600 --> 00:04:30,920
Speaker 2: anybody that used a cable in the last five years,

88
00:04:31,160 --> 00:04:34,599
Speaker 2: except maybe some of the cheaper imports. And if you

89
00:04:34,640 --> 00:04:36,800
Speaker 2: go back, drive by wire has been with us a

90
00:04:36,839 --> 00:04:39,800
Speaker 2: good twelve years, if not longer on certain models. So

91
00:04:40,680 --> 00:04:43,600
Speaker 2: drive by wire vehicle where there's a sensor on your

92
00:04:43,600 --> 00:04:46,200
Speaker 2: foot at the gas pedal, there's a sensor on the

93
00:04:46,240 --> 00:04:49,200
Speaker 2: throttle body. You move the pedal a quarter of the way.

94
00:04:49,200 --> 00:04:51,160
Speaker 2: The computer sees that and moves the throttle plate a

95
00:04:51,200 --> 00:04:55,720
Speaker 2: corresponding amount. That need to clean the throttle plate to

96
00:04:55,800 --> 00:04:58,720
Speaker 2: keep everything in sync becomes more acute as time goes on.

97
00:05:00,080 --> 00:05:03,599
Speaker 2: Most of the time, a throttle body cleaning requires a

98
00:05:03,640 --> 00:05:07,200
Speaker 2: reset where you're gonna disconnect the battery cables, jumper the

99
00:05:07,240 --> 00:05:10,920
Speaker 2: two battery cables together, lead the computer down, clear its memory.

100
00:05:11,440 --> 00:05:14,160
Speaker 2: Do that for five to ten minutes. You're good to go.

101
00:05:15,760 --> 00:05:17,440
Speaker 2: You're always gonna look for instructions.

102
00:05:17,440 --> 00:05:17,720
Speaker 3: I did.

103
00:05:17,760 --> 00:05:20,320
Speaker 2: I look for instructions for this accurate didn't find anything

104
00:05:20,320 --> 00:05:22,320
Speaker 2: in particular. They called for an IDOL relearn, which I

105
00:05:22,360 --> 00:05:25,120
Speaker 2: was familiar with, and that was once I cleared the

106
00:05:25,160 --> 00:05:29,599
Speaker 2: battery cables and did that reset, it was start the

107
00:05:29,640 --> 00:05:32,160
Speaker 2: car up, run under three grand till the fan cycles,

108
00:05:32,440 --> 00:05:36,039
Speaker 2: and then let it idle for five minutes. And that's

109
00:05:36,040 --> 00:05:39,359
Speaker 2: what I did, and we were good, sort of for

110
00:05:39,440 --> 00:05:44,240
Speaker 2: a while. P. Twenty two seventy nine I don't think

111
00:05:44,240 --> 00:05:48,120
Speaker 2: I'll ever forget this code. P. Twenty two seventy nine

112
00:05:48,200 --> 00:05:52,200
Speaker 2: is the onboard computer senses a vacuum leak in the

113
00:05:52,240 --> 00:05:56,160
Speaker 2: intake system, and that's what it came back with. Check

114
00:05:56,160 --> 00:05:58,800
Speaker 2: engine light on ran normal. It just set this P.

115
00:05:59,000 --> 00:06:02,799
Speaker 2: Twenty two to seventy nine. Time to do some research,

116
00:06:02,880 --> 00:06:05,359
Speaker 2: went back over my work, went back over the timing belt.

117
00:06:05,360 --> 00:06:07,160
Speaker 2: One of the things they point out as a possible

118
00:06:07,200 --> 00:06:09,440
Speaker 2: issue that will cause that code is if the timing

119
00:06:09,440 --> 00:06:12,159
Speaker 2: belt's off of tooth. Well it wasn't, and I kind

120
00:06:12,200 --> 00:06:14,400
Speaker 2: of knew it wasn't, but I'm obligated to check it,

121
00:06:14,800 --> 00:06:16,800
Speaker 2: and I did and it was dead square right where

122
00:06:16,800 --> 00:06:19,080
Speaker 2: it was supposed to be. But yet I've got this

123
00:06:19,120 --> 00:06:22,279
Speaker 2: twenty two to seventy nine fault code that could be

124
00:06:22,320 --> 00:06:27,159
Speaker 2: caused by that tea belt. Further research led me to

125
00:06:28,040 --> 00:06:30,960
Speaker 2: that the idle relearn is very specific for this car,

126
00:06:31,000 --> 00:06:35,960
Speaker 2: and I started asking myself, Yeah, hell, I discovered, and

127
00:06:36,000 --> 00:06:38,440
Speaker 2: it's not really talked about in too many places, not

128
00:06:38,520 --> 00:06:42,880
Speaker 2: even in factory literature that inaccurate such as this nature

129
00:06:43,080 --> 00:06:47,760
Speaker 2: has a reset for the throttle position sensor. So when

130
00:06:47,760 --> 00:06:50,400
Speaker 2: you clean the throttle plate and the new stop point

131
00:06:50,600 --> 00:06:54,560
Speaker 2: is not at one degree open but zero. Not only

132
00:06:54,560 --> 00:06:56,440
Speaker 2: do you have to clear the computer memory the way

133
00:06:56,480 --> 00:06:58,599
Speaker 2: I did it disconnect cables on an accurate Honda, you

134
00:06:58,600 --> 00:07:01,919
Speaker 2: can also there's a a function in scan tools, and

135
00:07:01,920 --> 00:07:04,960
Speaker 2: most scan tools have it called ECMPCM reset. You can

136
00:07:05,000 --> 00:07:09,880
Speaker 2: do that, but they also want you to zero the

137
00:07:09,920 --> 00:07:13,360
Speaker 2: throttle position sensor. Remember I said there's a sensor at

138
00:07:13,400 --> 00:07:15,360
Speaker 2: the pedal on your foot and a sensor at the

139
00:07:15,400 --> 00:07:19,000
Speaker 2: throttle body that have to correspond until the engine controller

140
00:07:19,240 --> 00:07:21,840
Speaker 2: where the foot is electronically so it can make adjustments.

141
00:07:22,440 --> 00:07:25,760
Speaker 2: You have to zero that adjustment and disconnecting the battery

142
00:07:26,120 --> 00:07:30,040
Speaker 2: doesn't do it. Disconnecting the battery can't because it's hard

143
00:07:30,080 --> 00:07:34,640
Speaker 2: written into the memory of the PCM. How good is

144
00:07:34,640 --> 00:07:37,880
Speaker 2: your mechanic? Well, only as good as a scan tools

145
00:07:37,880 --> 00:07:41,720
Speaker 2: as the answer I searched. Through all of mine nineteen

146
00:07:41,800 --> 00:07:46,480
Speaker 2: scan tools, only one aftermarket scan tool had the ability,

147
00:07:46,680 --> 00:07:48,680
Speaker 2: and that was the launch Tech X four to thirty

148
00:07:48,720 --> 00:07:52,280
Speaker 2: one tablet. It really gave me a new respect for them,

149
00:07:52,320 --> 00:07:56,040
Speaker 2: I have to admit, because having one of everything, they

150
00:07:56,040 --> 00:07:58,679
Speaker 2: were the only ones that did the engineering and brought

151
00:07:58,720 --> 00:08:01,560
Speaker 2: that product to market to help make me a good

152
00:08:01,560 --> 00:08:04,280
Speaker 2: mechanic and keep me a good mechanic by giving me

153
00:08:04,320 --> 00:08:06,760
Speaker 2: the ability to do nothing more than oh, I've got

154
00:08:06,800 --> 00:08:10,880
Speaker 2: to reset the TPS. Hit the button, reset, go through

155
00:08:10,920 --> 00:08:16,320
Speaker 2: the idle, learn we're done. The bottom line is your

156
00:08:16,400 --> 00:08:19,000
Speaker 2: mechanic is really only as good as a scan tool

157
00:08:19,240 --> 00:08:23,600
Speaker 2: or her scan tool this week says they are until

158
00:08:23,640 --> 00:08:26,840
Speaker 2: the next piece of technology comes into the door. And

159
00:08:26,960 --> 00:08:28,680
Speaker 2: I'd like to reach out and just say thank you

160
00:08:28,720 --> 00:08:31,200
Speaker 2: to the folks at launch Tech and tell them I

161
00:08:31,240 --> 00:08:33,280
Speaker 2: really appreciate the fact that they took the time to

162
00:08:33,320 --> 00:08:36,400
Speaker 2: put the engineering in there, and you guys did something

163
00:08:36,640 --> 00:08:39,800
Speaker 2: that no other scan tool company in the marketplace does

164
00:08:39,840 --> 00:08:43,000
Speaker 2: that I'm aware of, And I just want to give

165
00:08:43,000 --> 00:08:44,680
Speaker 2: you a tip of the wrench. You guys did a

166
00:08:44,679 --> 00:08:47,400
Speaker 2: good job. You help make me fix a car, and

167
00:08:47,440 --> 00:08:49,840
Speaker 2: you help make me look better than I actually was,

168
00:08:50,080 --> 00:08:52,520
Speaker 2: because without that tool, I'd still be sitting there going

169
00:08:52,840 --> 00:08:54,960
Speaker 2: how does it p Twenty two to seventy nine Get solved.

170
00:08:55,240 --> 00:08:57,160
Speaker 2: Hello and welcome Ronning any and the car doctor here

171
00:08:57,160 --> 00:08:59,520
Speaker 2: at eight five five five six nine nine zero zero.

172
00:09:00,000 --> 00:09:02,679
Speaker 2: Make your calls and answer your questions. I've got a

173
00:09:02,760 --> 00:09:04,720
Speaker 2: full slate of phone calls. What do he say? We

174
00:09:04,800 --> 00:09:07,480
Speaker 2: go to an early pause. I'll be back right after

175
00:09:07,480 --> 00:09:25,280
Speaker 2: this to talk to you on.

176
00:09:25,400 --> 00:09:42,280
Speaker 4: The streets over Runaway where Andrey, Hey, welcome back.

177
00:09:42,320 --> 00:09:43,920
Speaker 2: Why don't any of the card Ocutlet's get over and

178
00:09:43,920 --> 00:09:46,480
Speaker 2: talk to Tom oak Park, Illinois. Tom, Welcome to the card.

179
00:09:46,320 --> 00:09:49,800
Speaker 3: Doctor, sir, Good afternoon, Ron. I just wanted to tell

180
00:09:49,800 --> 00:09:53,199
Speaker 3: everybody when you talk about calling and leaving the message

181
00:09:53,200 --> 00:09:56,280
Speaker 3: for Fast Harry to call you back, Harry calls you back.

182
00:09:56,559 --> 00:09:59,520
Speaker 3: Harry called me back at seven o'clock my time, they

183
00:09:59,520 --> 00:10:02,720
Speaker 3: would have been eight o'clock his time on a Thursday night,

184
00:10:02,920 --> 00:10:05,079
Speaker 3: to ask to tell me about my question. And I

185
00:10:05,200 --> 00:10:06,240
Speaker 3: thought that was awesome.

186
00:10:06,520 --> 00:10:09,360
Speaker 2: He's the second hardest He's the second hardest working guy

187
00:10:09,360 --> 00:10:12,280
Speaker 2: in show business. I gotta tell you we love Fast Harry.

188
00:10:13,120 --> 00:10:15,240
Speaker 3: Well, so for all the audience to know that Harry

189
00:10:15,240 --> 00:10:16,000
Speaker 3: does call you back.

190
00:10:16,080 --> 00:10:17,320
Speaker 2: Yep, absolutely, thank you.

191
00:10:18,360 --> 00:10:23,160
Speaker 3: The question I had was on in September. September thirteenth,

192
00:10:23,200 --> 00:10:27,599
Speaker 3: you had an engineer to talk about powerframe grid technology

193
00:10:27,640 --> 00:10:32,080
Speaker 3: on new batteries, and my question is what brand name

194
00:10:32,160 --> 00:10:34,000
Speaker 3: batteries carry that technology?

195
00:10:34,520 --> 00:10:38,480
Speaker 2: Right now, the only brand name batteries that carry power

196
00:10:38,520 --> 00:10:42,360
Speaker 2: frame grid technology are the batteries that you're going to

197
00:10:42,440 --> 00:10:44,800
Speaker 2: get from advanced auto parts. To my knowledge, are the

198
00:10:44,840 --> 00:10:47,840
Speaker 2: only ones that currently have it. I believe there are

199
00:10:47,880 --> 00:10:51,800
Speaker 2: some other manufacturers lining up to take power frame grid technology,

200
00:10:52,120 --> 00:10:55,000
Speaker 2: but right now they're the only ones as of as

201
00:10:55,040 --> 00:10:58,120
Speaker 2: of our conversation, until somebody tells me otherwise. If you

202
00:10:58,240 --> 00:11:00,480
Speaker 2: want to read more about it, what you can do

203
00:11:00,559 --> 00:11:02,599
Speaker 2: is get out to the web and go out to

204
00:11:02,920 --> 00:11:07,199
Speaker 2: powerframe dot com and they talk more about powerframe grid technology.

205
00:11:07,200 --> 00:11:10,280
Speaker 2: And it's a great question because you know the thing

206
00:11:10,320 --> 00:11:14,560
Speaker 2: about that is, it's not just selling you another battery,

207
00:11:14,960 --> 00:11:18,000
Speaker 2: all right, it's somebody took the time to look at

208
00:11:18,000 --> 00:11:22,000
Speaker 2: the problem with batteries why batteries fail, and they came

209
00:11:22,120 --> 00:11:23,480
Speaker 2: up with they actually, they came up with a better

210
00:11:23,480 --> 00:11:25,520
Speaker 2: mouse trap tom. They came up with a better reason.

211
00:11:26,640 --> 00:11:30,640
Speaker 2: I think the only thing that limits more companies from

212
00:11:30,920 --> 00:11:35,440
Speaker 2: using powerframegrid technology is just the paperwork in between. And

213
00:11:35,480 --> 00:11:38,240
Speaker 2: I believe in time you're going to see all the

214
00:11:38,240 --> 00:11:43,920
Speaker 2: major battery manufacturers go to this technology. If that makes sense, well.

215
00:11:44,280 --> 00:11:45,960
Speaker 3: It makes a lot of sense. In that interview that

216
00:11:46,040 --> 00:11:49,680
Speaker 3: you had with that engineer was terrific. The questions and

217
00:11:49,720 --> 00:11:54,040
Speaker 3: how he responded was iles Marie to the radio because

218
00:11:54,120 --> 00:11:56,160
Speaker 3: I never knew there was that much Intel battery.

219
00:11:56,360 --> 00:11:58,680
Speaker 2: Oh, there's a lot into the battery. As a matter

220
00:11:58,720 --> 00:12:02,360
Speaker 2: of fact, Hey Tom, look at me, tom My. Tom,

221
00:12:02,600 --> 00:12:05,120
Speaker 2: can we put the powerframe and grid technology interview? Is

222
00:12:05,160 --> 00:12:07,920
Speaker 2: it up on the cardoctorshow dot com website? Tom My

223
00:12:08,360 --> 00:12:09,960
Speaker 2: chief engineer is going to take a look. If it's

224
00:12:10,040 --> 00:12:12,200
Speaker 2: not now, Tom and Oak Park, Illinois, and for everybody

225
00:12:12,240 --> 00:12:15,080
Speaker 2: else out there, we'll put it up on the cardoctorshow

226
00:12:15,120 --> 00:12:17,400
Speaker 2: dot com websites. Everybody that wants to can go out

227
00:12:17,400 --> 00:12:19,720
Speaker 2: and listen to it again. Because you're right, it was

228
00:12:19,760 --> 00:12:23,200
Speaker 2: a good interview, and that's one of the things that

229
00:12:23,679 --> 00:12:27,080
Speaker 2: we appreciate hearing. You know, we like to do interviews

230
00:12:27,440 --> 00:12:30,520
Speaker 2: that are going to be informative and sometimes fun. And

231
00:12:31,120 --> 00:12:33,240
Speaker 2: you know, when people react because you're not the first

232
00:12:33,280 --> 00:12:35,560
Speaker 2: person to tell us this, When people react like you

233
00:12:35,640 --> 00:12:39,640
Speaker 2: and others are doing, then you know, we want to

234
00:12:39,679 --> 00:12:41,319
Speaker 2: take advantage of that because our job is to just

235
00:12:41,440 --> 00:12:43,120
Speaker 2: educate you guys. We want to get you to understand

236
00:12:43,160 --> 00:12:44,760
Speaker 2: your car a lot better because there's a lot that

237
00:12:44,800 --> 00:12:47,600
Speaker 2: goes into batteries. There's a lot of things that go

238
00:12:47,679 --> 00:12:50,400
Speaker 2: into the simplest stuff. More than you know, I guess

239
00:12:50,440 --> 00:12:51,840
Speaker 2: if that's the proper way to say that.

240
00:12:52,520 --> 00:12:56,079
Speaker 3: Yeah, well, I just wish your show was available here

241
00:12:56,160 --> 00:12:59,199
Speaker 3: in Illinois. It is in some parts, but not in

242
00:12:59,240 --> 00:13:01,920
Speaker 3: the Chicago area. So the only time I get to

243
00:13:01,920 --> 00:13:04,679
Speaker 3: hear is when I'm driving across Iowa to get the Nebraska.

244
00:13:05,040 --> 00:13:07,480
Speaker 3: There's a couple of stations at Iowa to carry it. Well,

245
00:13:07,520 --> 00:13:10,520
Speaker 3: so you keep me company for that long drive across Iowa.

246
00:13:10,720 --> 00:13:14,640
Speaker 2: Well, I'll tell you what if you if you if

247
00:13:14,679 --> 00:13:18,080
Speaker 2: you care to let us know what radio stations out

248
00:13:18,120 --> 00:13:22,240
Speaker 2: there that are talk amr FM doesn't matter, and if

249
00:13:22,280 --> 00:13:23,960
Speaker 2: you think of it, send us an email Ron at

250
00:13:24,000 --> 00:13:26,160
Speaker 2: cardoctorshow dot com. Hey, Ron, I think you'd fit here.

251
00:13:26,160 --> 00:13:27,920
Speaker 2: I think you'd fit there. I'll turn it over to

252
00:13:27,960 --> 00:13:30,520
Speaker 2: the affiliations department and let them go bang on some doors.

253
00:13:30,840 --> 00:13:33,480
Speaker 2: Because you know, part of what this radio show about,

254
00:13:33,480 --> 00:13:35,720
Speaker 2: A big part of what this radio show about is you,

255
00:13:35,800 --> 00:13:36,360
Speaker 2: the listener.

256
00:13:37,480 --> 00:13:39,560
Speaker 3: You know, I just wish, I just wish there was

257
00:13:39,559 --> 00:13:41,920
Speaker 3: a show like yours here in this area. It's it's

258
00:13:41,960 --> 00:13:44,320
Speaker 3: a great show and I look forward to listening to

259
00:13:44,360 --> 00:13:45,160
Speaker 3: it on Saturdays.

260
00:13:45,160 --> 00:13:48,000
Speaker 2: I appreciate it, Tom, I appreciate that very much. Listen sir,

261
00:13:48,000 --> 00:13:49,320
Speaker 2: you have a good rest of the day. Thank you.

262
00:13:49,320 --> 00:13:51,640
Speaker 2: You're very welcome. Let's get over and talk to George

263
00:13:52,080 --> 00:13:55,200
Speaker 2: in Orrington, Maine, two thousand and one, Nissan Pathfinder. Hey George,

264
00:13:55,200 --> 00:13:56,760
Speaker 2: you're on with the card doctor. How can I help.

265
00:13:58,120 --> 00:13:58,160
Speaker 3: You?

266
00:13:58,240 --> 00:13:58,680
Speaker 5: Got ron?

267
00:13:59,360 --> 00:14:00,760
Speaker 3: Good listen.

268
00:14:00,800 --> 00:14:04,160
Speaker 5: I've been chasing this thing, this code for a long time.

269
00:14:04,200 --> 00:14:07,680
Speaker 5: It's a P thirteen twenty and it's put the stand

270
00:14:07,679 --> 00:14:11,720
Speaker 5: toool tells me it's a misfire or a ignition problem. Right,

271
00:14:12,080 --> 00:14:14,840
Speaker 5: car seems to run great, but I mean that this

272
00:14:15,000 --> 00:14:16,920
Speaker 5: code is that that have been chasing for a long time.

273
00:14:17,480 --> 00:14:20,040
Speaker 5: I've been listening on and off for years. And I said, well,

274
00:14:20,040 --> 00:14:21,640
Speaker 5: I'll give him a calm se if he can't help

275
00:14:21,680 --> 00:14:23,200
Speaker 5: me out to figure what his code is.

276
00:14:23,400 --> 00:14:26,480
Speaker 2: Okay. P thirteen twenty is a fault in the onboard

277
00:14:26,480 --> 00:14:29,520
Speaker 2: ignition system. This vehicle has coil on plug.

278
00:14:29,240 --> 00:14:33,040
Speaker 5: Correct, right, yeah, stick the coil pack six.

279
00:14:33,040 --> 00:14:37,040
Speaker 2: Six coil six plugs. Obviously have you changed the spark plugs.

280
00:14:38,040 --> 00:14:40,720
Speaker 5: I changed the plugs and I've also ended up putting

281
00:14:41,240 --> 00:14:46,160
Speaker 5: a new coil pack on one cylinder. Okay, did you put.

282
00:14:45,360 --> 00:14:49,239
Speaker 2: When you changed the plugs? Did you use the factory

283
00:14:49,280 --> 00:14:51,920
Speaker 2: brand plug? And this is one of those vehicles that

284
00:14:52,400 --> 00:14:55,520
Speaker 2: you know when we talk about using correct spark plug,

285
00:14:56,120 --> 00:14:59,240
Speaker 2: I want the exact plug that the manufacturer put in it.

286
00:14:59,400 --> 00:15:01,600
Speaker 2: I don't very that's what Okay.

287
00:15:01,320 --> 00:15:02,600
Speaker 5: That's what I put in it. I mean, that's what

288
00:15:03,040 --> 00:15:05,160
Speaker 5: I did that. I actually done it twice, and I'll

289
00:15:05,400 --> 00:15:08,200
Speaker 5: put it in it still seems. It ran fine for a while,

290
00:15:08,240 --> 00:15:10,800
Speaker 5: and then I got to be the code back up again.

291
00:15:11,160 --> 00:15:15,760
Speaker 2: The reason is this code sets. What they're doing is

292
00:15:15,800 --> 00:15:20,760
Speaker 2: they're looking at the firing capacitance or the firing capability

293
00:15:20,800 --> 00:15:24,960
Speaker 2: of each coil on a voltage drop a current limiting basis,

294
00:15:25,480 --> 00:15:28,960
Speaker 2: and the resistance value of the plug has been known.

295
00:15:29,080 --> 00:15:31,640
Speaker 2: It's it's almost like they made the parameter for setting

296
00:15:31,680 --> 00:15:34,680
Speaker 2: the code too tight of a window. If they opened

297
00:15:34,680 --> 00:15:38,480
Speaker 2: it up another ten or fifteen percent, you wouldn't have

298
00:15:38,480 --> 00:15:40,560
Speaker 2: a problem because, as you say, the car runs good.

299
00:15:40,600 --> 00:15:43,880
Speaker 2: It's just somebody's being picky here. You know, this is

300
00:15:43,960 --> 00:15:45,600
Speaker 2: like that kid that doesn't like to eat his line

301
00:15:45,600 --> 00:15:48,240
Speaker 2: of beans, but he has to eat him anyway and gag. Well,

302
00:15:48,480 --> 00:15:50,800
Speaker 2: they got to give him a bigger gag reflex, and

303
00:15:51,320 --> 00:15:54,600
Speaker 2: you know they're they're not doing that. So you know

304
00:15:55,240 --> 00:15:57,960
Speaker 2: this is a case that this P. Thirteen to twenty sets.

305
00:15:58,000 --> 00:16:00,160
Speaker 2: As a result, they see a current limiting issue on

306
00:16:00,160 --> 00:16:02,800
Speaker 2: one of the coils and it hasn't happened or gotten

307
00:16:02,840 --> 00:16:07,040
Speaker 2: bad enough yet that it flags a cylinder, but it's

308
00:16:07,040 --> 00:16:11,280
Speaker 2: still a problem. What scan tool? What scan tool do

309
00:16:11,320 --> 00:16:11,920
Speaker 2: you have? George?

310
00:16:13,880 --> 00:16:19,000
Speaker 5: The the OBT two. That's what I've used, Okay, And

311
00:16:19,720 --> 00:16:22,520
Speaker 5: I've actually had the scan tube plugged into the vehicle

312
00:16:22,560 --> 00:16:24,400
Speaker 5: as I was driving down the road to see if

313
00:16:24,400 --> 00:16:26,360
Speaker 5: I could give me some information on that.

314
00:16:26,480 --> 00:16:30,240
Speaker 2: And here's here's what I'd like you to Here's what

315
00:16:30,280 --> 00:16:33,880
Speaker 2: I'd like you to do, all right, if your scan

316
00:16:34,000 --> 00:16:35,760
Speaker 2: tool does. If not, you're going to have to dig

317
00:16:35,840 --> 00:16:39,640
Speaker 2: up one or find a shop that has one as

318
00:16:39,760 --> 00:16:43,640
Speaker 2: part of you ever wonder what makes a code set? Right?

319
00:16:43,760 --> 00:16:44,240
Speaker 3: Okay?

320
00:16:44,760 --> 00:16:46,320
Speaker 2: You know what are the parameters? Yeah, you go in

321
00:16:46,400 --> 00:16:48,520
Speaker 2: and unplug something. It turns on a check engine light.

322
00:16:48,800 --> 00:16:51,000
Speaker 2: That's a no brainer, right, The parameters are there. All

323
00:16:51,040 --> 00:16:53,240
Speaker 2: of a sudden it had connection. Now it doesn't. But

324
00:16:53,320 --> 00:16:55,240
Speaker 2: you know, it's kind of like when George gets sick.

325
00:16:55,560 --> 00:16:57,880
Speaker 2: George gets up on Monday and he's got a scratchy throat,

326
00:16:57,880 --> 00:16:59,200
Speaker 2: and he gets up on Tuesday and he's got a

327
00:16:59,280 --> 00:17:01,480
Speaker 2: running nose, and he's gets up on Wednesday, Andy six.

328
00:17:02,040 --> 00:17:04,639
Speaker 2: Those are the events leading up to the failure. A

329
00:17:04,720 --> 00:17:07,720
Speaker 2: computer does the same thing. In car language. We call

330
00:17:07,760 --> 00:17:11,560
Speaker 2: it mode six, and there are scan tools out there

331
00:17:11,600 --> 00:17:14,960
Speaker 2: that will read troublecodes data stream and mode six. Mode

332
00:17:15,040 --> 00:17:18,679
Speaker 2: six being the machine language behind the scenes of the

333
00:17:18,760 --> 00:17:22,800
Speaker 2: failure as it occurs. I'd love to see Mode six

334
00:17:23,080 --> 00:17:27,520
Speaker 2: testing of this vehicle, and there'll be PIDs that start

335
00:17:27,680 --> 00:17:29,919
Speaker 2: at PID fifty two and work their way up the

336
00:17:29,960 --> 00:17:32,199
Speaker 2: scale fifty one and fifty two, and then work their

337
00:17:32,200 --> 00:17:37,120
Speaker 2: way up to scale which cylinder is flagging more as

338
00:17:37,240 --> 00:17:42,639
Speaker 2: a failure. And for example, you may see a mode

339
00:17:42,680 --> 00:17:46,919
Speaker 2: six test result that shows you cylinder six has repeated

340
00:17:46,960 --> 00:17:50,240
Speaker 2: misfires but not enough to trip the code, but it

341
00:17:50,280 --> 00:17:53,119
Speaker 2: will set a thirteen twenty. I'd go write the cylinder six,

342
00:17:53,480 --> 00:17:56,199
Speaker 2: take that coil, move it from six to three, and

343
00:17:56,280 --> 00:17:59,199
Speaker 2: vice versa. Does it follow the coil? If it follows

344
00:17:59,240 --> 00:18:01,439
Speaker 2: the coil, that coil is the one that's failing and

345
00:18:01,520 --> 00:18:03,800
Speaker 2: causing the problem for you. I'm not a meeting in

346
00:18:03,800 --> 00:18:05,399
Speaker 2: the car doctor to put back right after this
