did you clean the IAC motor seat? and did you reset the computer so it will recognize the new part? If you did both of these, I would check for a sticky EGR valve next.

I cleaned seat with carb cleaner, by reset computer do you mean unhook batt. yes. New problem, check engine ligtht, came on, map sensor. Replaced sensor, reset computer. now on occation I get a vac howl around the egr. when you put pressure on in the noise changes. Also carb cleaner will bubble at the base, but does not change rpm's
