Usually I would not post in this forum but this involves a 92 EG8 M/T. I need a common reason why the check engine light would come after the car is warmed up, no consistency though. Goes off when the car is turned off. Read in the search achieve that a bad ecu might cause this? Any input is appreciated.

 

Pull the code, and list it here. Without it, there really isn't any way for someone to make suggestions here.

 

Yeah, butthead! uh uh uhhhhhhh

 

oxygen sensor needs replacing thats what happened to mine and it was that if thats not it then use a paper clip to short the ecu to spit out the code by flshing the check engine light idk exactly where you stick the paper clip but u can just look it up somewhere
