Sorry to hear about all the health challenges, OldBlue. Glad for you that you’re in Canada. Thanks to our health care system I have mountains of paper, and it’s not currency.

I said it was easy to check the ethanol % setting, not to reset it. If it’s not off, move on. If it’s off, certainly worth the trouble to reset it. Dealer did it for $65 or something. My trusted shop says they would have done it for free, since I already had a diagnosis.

I said something inaccurate - my PM conversation was with Blownz, not the OP.

 

Ok, then it’s not an easy fix , as you require a dealership level scanner.

Thanks about Sweetie’s ongoing battle, but her chemotherapy will be done in March, her cancer was removed Oct 28, 2021

 

Alcohol was at 55.3! So found a local shop owner who I kinda know. He said yep just fixed a Silverado with that issue. Made appointment. Coworker wanted to buy a SnapOn Solus Legend scanner. So we hooked it up, went to fuel management and reset alcohol content to zero. Erased CEL. Engine started perfect and I drove it that day with no issues. Next day drove it 160miles without it missing a beat. Temps also stayed exactly normal like they should. Came home and drained marvel and oil out. Old filter was kinda beat up looking never had that happen before anyhow added new 5w30 synthetic and filter.
So long journey is over thanks for everyone’s help and idea. To the OP and Pulp you guys were right the alcohol content did have something to do with part of the issue. So either the gas station I found out is junk it’s gas messed stuff up or me running 89 forever and switching to 87 with gas prices somehow upset the alcohol sensor. We will never know but glad I talked to people about changing gas stations and wonders why pumps were never packed at this place. Just was closer on my route to work. NEVER AGAIN!

 

I added in the photo of the scanner showing the alcohol percentage.
sorry but that erased some text above that,

He wrote about how it was fixed, his P0014 code was the exhaust VVT solenoid, he changed it.
the coolant temperature sensor was black , not reading correctly, he replaced that, along with a new thermostat from AC Delco and fresh Dexcool 50/50 mix coolant



coolant temperatures read more stable now.

 

Thanks for doing that blue! Also when I changed the oil it smelled horrible like strong gas vapors. YouTube mechanic said that’s normal with this alcohol issue and change oil right away once issue is fixed which I did after marvel got into the engine more for the long ride. Drained oil and looked normal with no sludge in it and drained quick. Forgot to mention this is the longest trip the engine has been on since 2017 for a 12hr drive. Hasn’t been driven much for a year and now just short trips. But the engine ran quite compared to normal on the long trip yesterday which just could be from all the issues that went on being worked out and extra richness being burned out of the whole system. Through this whole thing the new plugs were still spotless.

 

The engine ran quite... quite what?

 

Meaning it sounded healthier once fixed.

 

Those typos! Quiet is what I think he meant.

 

Yes forgot to edit haha.

 

With your HHR fixed what else do you have to do ? Edit and enjoy the ride!
Those short trips may have been the cause of the alcohol percentage problem, the engine and O2 sensors not getting up to temperature for a long enough time!
