I have this problem that i can't figure out. I have replaced the IAC valve twice within a one yr. period and my truck has about 105k on it. My problem happens when i put my tranny into park and the rpms drop down to 450-500. My TB is pretty clean, the MAF has not dust or oil build up. what could b causing this?
