I have a 1994 Ram 1500 4wd with a 5.9 L. I recently replaced the IAC with a new one and the TPS with an old one that still works. I've also replaced the TB gasket (twice cause part of the replacement cracked.) and cleaned the throttle body thoroughly. I've checked for vacuum leaks with carb cleaner but still have a high idle. I can still hear a another vacuum leak but unable pinpoint it. It smoothed out after replacing the IAC. It should be running between 500-800 at idle in part unless I am mistaken. However it starts at 1300 and climbs to 1500. Any ideas? thanks.
