i thought it was the silver thing under the throttle body with two coolant lines running to it, but would like to know for sure. cause when i put my car away for the winter the idle would rev between 800 and 3000 rpm. i put the smoke machine on it at school and didnt find any vaccum leaks. i just did a head swap so i know all the gaskets are good. and yes it was doing it before i did the head swap. ive cleaned the IAC and even tried another one i had. checked the voltage at the iac and it was in spec so that lead me to the internet and the fast idle valve.
