My idle was faltering below 500RPM's. I cleaned the throttle body and the IAC port, extremely well. Then the idle would stay at approximately 1000rpms. So I hooked up a scanner to the engine diagnostic ports. It concluded that the motor was not going into closed loop and that the O2 sensor was to blame. I replaced the O2 sensor and that would let the motor into closed loop, and it dropped the idle to about 900rpms give or take 50 rpms. It is still to high so I replaced the IAC stepper motor and it is still at 900rpms give or take 50.
What are your takes on this?
Let me know.
