Noise problem solved. GM had an update to correct programming in the ANC (Active Noise Cancellation). The excess howling in very cold weather is gone. Took about an hour. Re; not shifting into 8th gear. Received a technical bulletin indicating customers may raise the issue of not shifting into 8th gear.

I have a problem with the TPMS on my 2018 Equinox 1.5 liter. I am getting the dashed lines for all 4 tires. It started out with just one tire on the rear passenger side then the front passenger side went

I've decided to replace the fuel injectors. Found the pcv port almost plugged up and the valve cover breather line almost plugged. The data that I've collected suggest a rich condition when the stalling occurs. I've already replaced the high pressure fuel pump and isolated the EVAP and electrical systems. If this doesn't work the only thing left is the ECM.

Ok. found the problem. After changing multiple parts and no codes. I started unplugging one thing at a time and running the engine. Found to be a bad oxygen sensor. this was a brand new Denso oxygen sensor. no more problems.
