Question about 2001 Cadillac DeVille
Yes its very possible that the IAC valve is bad.Here is something you can try.Take the connector off of the IAC if this remedies the situation then replace the IAC.If the idle is surging then I would look at the throttle position sensor.And also remember that if a sensor was bad you would get a check engine light that should come on.You might also have a vacuum hose that came off.
