Sbourg,

So, I take it that is nothing wrong with the ICV!! The ICV does what the the ECU is telling to do.

The temperature sensor is brand new. The AF potentiometer is good, I looked at it, and there is no defect that the eye can see. I also placed the potentiometer where it read 400mv, between pin 1 and 2 ignition on engine off. The car starts every time, cold or hot, runs very good thru out the whole range, no miss whatsoever, not bad for a 208,000 miles!!! ( knock on wood)

You have mentioned about the O2 sensor, this could be the culprit, I have not replaced it in ten years of my ownership. I would like to disconnect the O2 sensor and see how the idle would behave. Would you happen to know where this O2 sensor connector is???
Thanks in advance
Alex
