2 YEARS OF PARTS CANNON - Part 2 (Chevy Malibu Intermittent Stumble, No-Start P0106)

[@RJ-vb7gh]

Back in the day, the difference between a $1500.00 car and a $1.00 car was whether it started or not. Junk yards used to charge to tow cars away. I learned diagnostics early and you should have seen the faces on people who sold me cars when I fixed and started them and drove them away. I got one $1.00 car because it had a broken choke pull off vacuum line. It started but stalled out when you put it in gear. Diagnostics are the difference between a smart mechanic and a grease monkey. Which is why after 45+ years of working on cars, I watch your videos to try and stay current... and keep my mind working in my old age.

Ivan is that one guy who always pulls their Pico scope out at the party.

[@vicarod]

What surprises me is how quick garages are wanting to throw parts at problems. Between you, Danner, both Erics and a few others...I've learned that if a vehicle is throwing multiple codes, the parts cannon isn't going to fix the issue. Because of your channels, my brother and I were able to troubleshoot my 77 yr old mother's 2010 caravan (with me living 4 hrs away). We read the codes her van was throwing...I did some research on the problems and found out about a couple of connectors that have corrosion issues. Opened them up and found corrosion and lack of continuity. Cleaned up connectors and she's back on the road. We will replace connectors when I can get up there. Had we just read the codes, we would have replaced a MAP sensor and EGR valve, neither of which would have fixed her problem. Thanks Ivan!

[@screamingflat6]

Lol this is still part changing not trouble shooting 😅

[@EddieLeal]

Well, while I don't justify the reason because it hurts the customer, I can understand why techs do this. It has to do with how some techs are paid. Dealership techs are typically paid a flat rate. They are paid a set price for the job done. If they have to spend too much time in diagnostics they are not likely to make that much for that day/week. They'll be stuck on one vehicle that may not garner them much income. So, they may feel compelled to rush the diagnosis, toss parts at the problem and hope they get lucky and resolve the issue. Not in the best interest of the customer but I feel its the main reason why some techs may rush/throw parts at vehicle problems.

[@markmalikowski4971]

Once again I am amazed at how many times you have required no parts to get the job done. Well done!

[@nickbee1291]

So the CAN codes setting in other modules when an Engine DTC is set is going to be more commonplace with the implementation of driver safety aids in newer vehicles. When a module set a DTC that could impact ADAS systems and vehicle power control you will get sympathetic DTCs in other Safety related modules like ABS, Blind Spot, Lane keep assist, etc. You can talk to all the modules on the network and the CAN patterns will look perfect as you found, but the modules are not happy with the data being sent from in your case the ECM. I see a lot of techs get tripped up by this when they pull all these CAN signal DTCs and over look the one or two engine related DTCs. They just get hyper focused on the CAN codes without understanding why they are set and usually start loading the parts cannon. Great video!

[@josephwash109]

The communication code may have been a default strategy for the PCM. Maybe the intermittent drop-outs of the signal caused the PCM to question the validity of the data it was receiving. With the CAN bus DTC set, the PCM probably started ignoring real-time data and did internal calculations instead.

[@adotintheshark4848]

With the way the wires are run and with a lot of the harness "dangling", there's going to be a whole lot more broken wires in this car.

[@2aminitials]

When I saw "bonus footage" I was hoping it was footage of Diagnostic Dog putting on the missing wire loom and electrical tape.

[@psdaengr911]

I understand why he didn't. Particularly on an older car, messing with wiring that isn't in the immediate area of repair or directly related to the circuit being diagnosed cause new problem. It's bad enough when you need to take apart one multi-conductor connector because of one already-failed wire. (The probability of another wire breaking as you work on it increases with the number of conductor.)

[@jamesnall569]

I had an 09 Malibu that was reliable for 65k miles before I traded it in for a 2013 Honda Civic. I bought the Malibu with 116K miles and traded it in with 180K miles. I had the car for 4 years and the the only thing the car needed was A and B actuators and the fuel pump replaced due to fuel line leak in the 4 years of ownership. I did the regular maintenance and I got lucky with this Malibu.

[@tomlewis3658]

After I watched Part 1 last night, I was thinking I hope Ivan doesn't string us out for a day or 2 - now we have Part 2, great. That was a nice diagnosis & fix. It's too bad the wiring failed the way it did here, and we hope for the owner's sake that this doesn't happen at another harness. My only 2 cents worth of opinion is that I was watching the work going on near the open throttle body, and thinking it would be safer to cover that open throttle body with something, so that nothing (like a snipped off wire or insulation end) could fall in there.

I buy cars, often used. A single car owner, I keep them until they become unreliable or expensive to keep running. The American car brands were the least reliable.

Something to consider before hooking up BOB and ur scope..

[@dennisthomas4766]

I had a 06 colorado that had a stumble and misfire at 3500 rpm and up and what I found was the map sensor was in it's holder but leaking vacuum at the intake so I took wire ties and pulled it tighter into the intake and that took care of it. Somebody before me changed the map sensor so it was new. Funny how a map sensor can make the engine do strange things.

[@adamtrombino106]

GM has gotten very critical about MAP vs MAF readings, whereas before they used MAP more for elevation trim corrections, and MAF for major fuel/timing almost exclusively. Now the MAP vs MAF must be within spec, or the cars/trucks will act very stupid, if they start and run at all.

I wonder if GM has an inherent problem with those connectors and has or will in the future issue a service bulletin on the problem. This is the second one you have seen with this connector being an issue, well the terminal anyways. This would be a perfect reason to come out with a bulletin for a problem such as this. I wonder if the tps codes set because on some vehicles the tps and map sensors are compared to each other and should be in a certain range of one another.

Def glad I didn’t go Malibu the more I hear how bad reliability is on these

[@adamtrombino106]

Those engines need a lot of careful maintenance, and oil changes are paramount. GM has loads of trouble with that intake system cracking which forms vac leaks and false MAF codes, exhaust manifolds cracking sometimes leading to O2 sensor lean codes, and tons of wiring issues.

[@kdmq]

A generic tech tip for the viewers: I have seen, and heard of, many cars with intermittent faults that act up several times a day for the client, and, every single time they bring the car to the shop, the fault does not happen, even when the technician is diagnosing for hours. One might think that this is a petty act of God, but I've found that the cause is the simple fact that the technician opens the hood, and causes the engine bay to be significantly cooler than when the client drives the car. If you ever get a car that will not act up for previous shops, but always acts up on the client, always close the hood down while idling the car, even if you have test leads and a scope hooked up. Just make sure not to crush the wires.

Not being critical, just wondering why you did not just repair the broken wire rather than removing and replacing it. I do understand that the result is a slightly longer piece, but it seems that there would be an easier way to repair it by inserting a jumper between the 2 broken ends.

I think he cut that wire in part one. So I assume the connection in the weather pack was bad and causing the intermittent problem. Edit: I stand corrected

[@paulmonk7820]

@@_RiseAgainst Yeah, it did look like the crimp at the pin was loose, but there didn't seem to be any break in that area, at least none that I saw or that he mentioned. It looked like it finished breaking when he pulled on it. Doesn't seem possible, but I think the actual wire was already broken, and he just separated it by breaking the wire covering.

[@PineHollowAutoDiagnostics]

The break was so close to the connector that removing the pin was the only reliable option for the repairs 👍

[@psdaengr911]

Varying resistance means that several stands of the wire were broken internally but not necessarily all at one location. The most likely cause was stress. Making two spices close to the pin is not as sure a repair as one splice that replaced all the copper entering the pin. (imo The new lead should have been longer to move the less less flexible splice farther from the connector where the stress had already caused damage. )
