96 Blazer grounding problem maybe
Hi folks, I have a 1996 Blazer 4x4 that's been having issues with stalling and also idling way to fast. The computer keeps throwing a 0122 code but when I check the TPS with a multimeter everything comes back within specs.
If I recall there was a discussion on another forum about these computers using the fuel tank pressure sensor as part of this circuit, so does anyone know what sections to check for bad grounds.
Also is there a way to check the computer for internal grounding issues?
Thanks in advance.

Follow the flow chart in this link and you'll find the problem, guaranteed. The flow chart is straight out of the GM factory shop manual. https://blazerforum.com/forum/diagno...plained-35161/
