Hunting Idle
Hunting Idle
Still battling this beast. Infamous hunting idle. Stumbles a bit from idle to acceleration also.
No vacuum leaks, replaced IAC valve, ECU, TPS, O2 sensor, and bled the coolant. I do have a tiny symptom.
It used to throw a code and then the idle would be fine until I turned it off and restarted. This tells me the ECU is falling back to the nominal fault value for the idle injector pulse width because it throws a code.
It also tells me something is telling the ECU to vary the pulse width on the idle injector.
Turning the AC on and off has no effect.
What else might be telling the ECU to vary the pulse width on the idle injector.
TIA Kevin
