Is there something that could be shorting out the Idle Air Control valve? Does it have a fuse somewhere? Or else, how long after replacing that does the issue disappear? I replaced the IAC valve and there was no change.
So far I've replaced half the plugs ( the ones I could reach ) but none of them seemed to be having any issues. I replaced the fuel filter. I checked the distributor cap and rotor, no problems there. There are no vacuum leaks, and the throttle body is not clogged. The air filter is also clean.
ernie1: When you replaced the IAC valve, did the issue go away right away?
What else could be causing the problem? It won't idle at all. I have to keep it in park or neutral and keep revving for the engine to stay running. And it starts to hesitate when coasting once the RPM gets down to a near idle.
