Ok i bought a IAC restritor gasket... installed it.... now my car idles like 1400rpm??? Only way i could get it to idle right was plug the IAC vacuum line... Is there any harm in running like this??? how do i get it right? i like it not taking 10 years to idle down..

Well i made a plate for my car, and it did the same thing. I played with trying to find the right way on making the "smaller" of the 2 holes larger, untill the car ran right again. Another thing you wanna try is, disconnecting the battery (iam sure you thought of this but just for the record lol)

I tried the battery thing... Finaly tried sticking a plug with a small hole drilled in it into the vac line for the IAC and got it idled down to about 900 so going to see how it does today on my commute might have to make some adjustmentts..

Why does the plastic plug on the top of the IAC always sound like a vac leac?
