Question about 2004 Chevrolet Impala
I had a code for a bad IAC. I installed according to instruction and now the car doesn't idle until warmed up. Could the IAC be bad but not bring back the code
Hi! The IAC (idle air control) cant be bad since you replaced it for a new one. But I do suspect a faulty MAF (mass air flow) sensor, It has big contribution on engine performance specially on the idling. This may not give you a code but since you described your problem clearly I would suggest that you replace the MAF, it may not die now but sooner or later it will. Hope this helps and have a good one!
