BTW it has been raining 1998 Contour V6 2.5L ATX

No throttle hang so i don't think it's the IAC, My questions is: is there a coolant sensor that indicates that the car is cold and other temperature sensor that says the PCM that the engine is warm? (and of course the temperature sensor is bad) 1998 Contour V6 2.5L ATX

That's not going to be your problem though I'll bet... I agree with Gregg that it's your IAC. The IAC going bad or getting dirty doesn't always result in throttle hang. I just had to replace my IAC for the same reasons you're describing... stumbling idle, searching a bit while it's cold. I would have just cleaned it and reused it, but since I have 10 or so laying around, I thought what the heck... http://www.bnmotorsports.com "And I will strike down upon thee with great vengeance and furious anger those who attempt to poison and destroy my CEG brothers.

(and of course the temperature sensor is bad) Yes, it is in the back of the coolant distribution housing and is hard to get to without removing a lot of parts. But the guys are right, if you have a high cold idle it seems to be working. The IAC may be sticking. A little carb cleaner in the inlet hose is usualy enough, or you can take it off and clean it better. My experience has been that cold idle fluxuations that are slow (5-15 seconds) and worse in gear are usually vacuum leaks. More than once I have seen the idle smooth out by pressing down on the upper intake manifold. "Those who cannot remember the past are condemned to repeat it" -George Santayana
