"... everything seems to be happy... Maybe they replaced all the right parts." :-) Always satisfying to see a successful Keith Tug-Test. Nothing wrong with a good Cliff-Hanger. When the owner arranges for a 3-hour tow, ya gotta believe the problem is real. Nice work.

That a customer was willing to tow a car for 3 hours in order to reach Ivan's shop is the most sincere compliment to Ivan's skill as a diagnostician.

Ivan, thanks so much for making and posting these videos. I can't tell you how much I learn from watching them. My son's car had an intermittent problem which we chased for over a year, and replacing the engine wiring harness finally solved it. Had I known the "tapping" and tracing techniques, I probably could have fixed just one wire!

Ivan you work on many different cars under many different circumstances and still manage to get to the problem!! I also say if ya find the problem you can fix it too! Finding the problem isn't always that black and white. Keep on diagnosing and bringing great content to this channel.

I had a Malibu Ecotec with similar symptoms, No codes. I noticed they only happened in the hot part of the day. I reached way back in my brain to remember back in the 60s and 70s we called that vapor lock. Well, to fix that we'd install electric fuel pumps as pressurizing the gas raises the boiling point. But the Malibu has the pump in the tank. I realized that the gas we use has alcohol in it which lowers the boiling point of the gas. Switching to alcohol free gas solved the problems. Really only needed it in the summer months. I should note that at the time I was at elevation in the Denver area so that exacerbated it.

That Thinktool scanner looks to be fully featured and fast. I'm tempted but it's a lot of $$$ for just a DIY guy. If I had a weekend business or a fleet then I wouldn't hesitate. Being able to force switches and such is a very powerful troubleshooting tool.

Once again you have given enjoyment to an old tech. Gotta say kinda over the heartbeat of China!

Your videos have given me some excellent information.

We want part 2, we want part 2, we want part 2! Lol! All the drama and twice the fun with Ivan!!!

Good to see your still at it. Keep it up brother.

Excellent case study, possessed car, lol!!! Waiting for part 2!

check the harness near the oil filter, sharp edge on block. also follow back front o2 sensor wires under coolant tank rub point back there.

This is going to be a good one. Watching as I type... 🤣😂🤣😂

Wow Ivan......chasing it down. GO BIG RED GO.

Fascinating. I saw that baro reading at 14 in the beginning and though that was odd. Thanks Ivan!

I just did a timing job on a 2012 malibu a month ago. It had a map sensor code in it also. 2 previous shops had replaced the Map sensor in effort of repair. I also replaced it with aftermarket (it was cheap and easily changed) so I took a chance. Car came back 2 days later with Map codes. I replaced it with a used OEM unit and have not had any issue.

NOW you've got my attention! On to part 2!

Hello Ivan from Australia ;) Part 2 oh no I was just getting nicely into that 🤣😂
