you may also want to check for a disconnected vacuum hose or cracked vacuum hose, you'll hear a hiss or high pitched wistle, or you can take a can of brake kleen and spray it around the intake manifold and the vacuum hoses. if you hear the idle change then that is where your leak is. otherwise here is your diagram of the IAC
