    Default High idle 84 Crossfire TBI

    I recently replaced the IAC valves in my TBI. Now the car is idling at 2500 rpm’s. I have removed and adjusted the valves 3 times. Initially the idle is around 1000 then it creeps back up to 2500 and stays there. Any suggestions?

    Did you use a quality part made for your engine?

    I've replaced and even cleaned these valves on other engines and have not had your issues before.

    Could there possibly be a relearn that's needed? I don't have access to your Vettes serv manuals.
