    What should the idle be set at?

    Can anyone tell me what the idle is supposed to be set at for a 1986 MGM with the 5.0L motor? This weekend going to pull the iac back off,clean everything out,and check a few other things. I want to see what the idle is set at.

          672 actually. Its self-adjusting. That screw is not an idle adjustment screw. The computer takes care of things with the IAC.

              reguardless what monitors it there should be a sticker on your fan shroud or under hood that gives you this info along with timing, plug gap ect.

                i think all it says about idle is that its not adjustable.
