Customer Ready to JUNK This Malibu? (Intermittent REDUCED POWER)

[@vernowen2083]

Ivan, I have a 2012 Jeep Wrangler Sahara. It was suffering from stalling under heavy loading yet triggered no codes. I took it to my mechanic and all he could see was the fuel pressure was on the low side and recommended a new fuel pump. I was watching Eric O working on a same year and model Jeep and his problem was a bad ground. This led me to go looking for the ground on my fuel pump. As Eric O would put it, it was a green puss sack. Repaired the ground and now there is full fuel pressure, and it no longer stalls under heavy loading.

Great patience and detective work . Unfortunately , whenever the " wrong hands " touch anything , it only makes things more difficult .

Obviously , when mounts wear or items are " rerouted " by EXPERTS , the damage begins .

[@christophermurphy943]

I can relate. Vibration and dirt are EVEN bigger problems on construction equipment. If split loom harnesses are used, the edges of the split loom, with the help of the dirt and vibration , act like teeth and wear into the wires. AND, the only way to find the damage is to remove clamps and remove the split loom.

[@dereks.6783]

Being a car from Philadelphia, it's not surprising that the turn signals and headlights don't work. We have a Police force that's not allowed to pull people over for inspection issues anymore. You can have expired inspection and emission stickers and the Police can't pull you over because it is believed that it is racial profiling (it's actually called The Driving Equity Law). There are thousands of cars driving around Philly that haven't been inspected in years and are so unsafe. Ivan was so worried about taking that car on the road without turn signals and headlights but if you were in Philly you'd have no worries. It's insane! You can see that the Owner never even mentions the turn signals or lights. It's hilarious. Great work Ivan!

I had a very similar problem with my daughter’s 2011 Malibu with the 2.4 engine a few years ago. The local dealer tried the parts canon for 2 years but could never find the real issue causing the intermittent reduced power. After researching it online, I discovered the only people who seem to fix this issue replaced the faulty battery cables on this car with non-OEM cables and cleaned all 5 grounds. I did the same and it has now been over 2.5 years, the car has run flawlessly without a single reoccurrence. If one cannot find a bare wire or short, this would be another option to try since it has worked for a number of us.

Had intermittent proble.m with my 09 Yukon, 5.3ltr. some days fine, then start again and dash lites go crazy, abs, trac control, no tach no speedo, hunting idle. Changed cam and crank sensors, new battery. Fine for a few days then here we go again. Finally found that a sluggish starter was the problem all along. The computer wasn't seeing a good crank up and everything went nuts. Starter/alt shop rebuilt starter and problem solved. GMC dealer wanted to fire the parts cannon to the tune of $2500 when.

[@autotek7930]

If you doing calibrations on cars that are not fully assembled you definitely are not following si for calibration procedures and requirements, in fact you may be delivering unsafe cars to customers by doing them like that. It might pass but will not be accurate, just one degree for the front radar at 100 yards will cause the radar to not pick up the car in time to adjust and especially work in emergency stop conditions. You really need to rethink your choices before you get someone hurt or killed

[@rhkips]

@@autotek7930 I'm well aware of such concerns, and always take things like that into account. I will not perform ADAS calibrations in situations where the state of the vehicle will alter said calibration, and in this particular case, despite the state of the vehicle, all pieces necessary were in place. There's also the trust factor with the shop, and every shop is different. This particular shop communicates well and understands the implications of post-calibration assembly or R&I, and I've worked with them in situations like this before. They reach out to me before delivering the vehicle and go over work performed after my visit to verify. This is very much not a common occurance for me, and I turn away more vehicles for calibrations in a week than I have accepted in an imcomplete state my entire career. :)

For 2011 GM the real time data (live data) rate should be fast enough to see even short +5V VREF drop outs using a scan tool, but I do applaud your use of the PicoScope for corroboration, so well done Ivan. The first basic check is the battery cable connections, condition and do they follow the vehicle electrical diagram. The Battery Neg lug should be replaced. The screw clamp style lug that replaced the factory crimped lug is crap (when used I also suspect a crap neg battery feed cabling). ECM sensor wiring (like the MAP sensor wiring) should use at least plastic or friction tape wrapped high temp plastic loom to protect the wires. Wire feeds are never routed on the engine without protection and are secured as to not move due to engine vibration which could result in chafing. The MAP wiring is wrong and highly suspect as a candidate for chafing. Any bad or missing loom should be replaced. The chassis ground across from the ECM has some green crusties. The headlamp pigtails are readily available. Even the actual OEM style are not that expensive. You can use a Borescope camera to inspect wiring on the top of the fuel tank without having to drop the tank. For older than 10 year car rust belt repairs which I did for about 20 years until seeking some sunshine, the inspection will usually result in bringing the vehicle wiring harness back to a reliable factory condition, or at least as good as a repair can be made, in one way or another, usually resulting in a small list of needed wiring repair, which needs to be done if you want to provide a warranty on repairs, because if the car stops working within the warranty time it is coming back to you. For 2011 ECM avoid shorting 5V VREF to ground as a diagnostic test. It is current limited, but the circuitry is not as robust as to support a short to ground as a test, the voltage regulator may just fail due to heat.

Hello my friend your just the man im looking for!!! Please 🙏 help my battery cables ends would not tighten the alternator was changed twice the battery twice the starter also!!

Really liked this video and learned a lot. Seems thats all i ever dealt with was intermittent issues But that was mostly before CAN when there was lots more wiring and connectors

Customer replaced engine mount was my first go to for engine harness because of excessive movement and pulling and rubbing being amplified.

The car feels happy and the machanic too 😉

Congrats on your abilities as they are hard earned. You would do your community a service as an instructor in your local CC as an instructor in their automotive program. You're really good at it. If you can keep my attention..... Too bad it would be a significant cut in pay.

thats one well used malipoo, def been in a front and rear accident, seatbelt retractor is probably blown and they just unbolted the one end, gas tank leaking from a rotted sending unit/pump, wiring harness is about to grenade, but gotta have that ac working!!! how long does it have left before the timing chains blow thou? lol

What I picked up on this diag is that the throttle redundancy is split on two independent circuits not just two inverse "pots".

[@PineHollowAutoDiagnostics]

Depends on the manufacturer 👍

[@raymondhorvatin1050]

Nice work the stubborn thorough approach works thanks for the trouble shooting lessons

Hi I was surprised you didn’t wrap that part of the engine harness where all of the cable wrapping had deteriorated too !
