I took it in to get a diagnostic and the code was in the fuel managmant is what I was told more specifically that the motor was running lean and that it had to go to a dealer that had a crossfire tech on staff. I scheduled it at a dealer with a crossfire tech on staff for a week later. The whole time the light was on and the evening before I take it to the dealer the F$&^%G light turns off.

Well the dealer got the same code when they did the diagnostic but since the check engine light was off they couldn't replicate the problem to figure out what was wrong so needless to say it wasn't fixed. The next day the Friging light came back on again!!!!

So before I go through all the BS of going back to the dealership and leaving my car there for the whole day again. Has anyone had this happen and what was the problem? Thanks for your help.

If the engine seems to run fine even thought it is running lean, it might be an O2 sensor failing.

Then again, I could be wrong!
