Just wondering what is up with this: when cold no check engine light, once warm check engine light flashes but does not stay on. The ecu is not throwing any codes.........any ideas?

 

anyone...............

 

you try swapping a known good ecu in?

 

Yeah try replacing that ecu.....it could be fried and could be jus throwing that code. Is your car acting any different with the check engine light on?

 

ECU doesnt flash any codes, when I start the car in the morning, it is not on. As soon as it is warm and I start driving , the check engine light flashes but never stays on. The car runs fine other than the gauge cluster not lighting up when I turn the lights on.
