I have searched the forums and have found a few posts on this. so here is my question, Is there a procedure for setting the base idle on 89SC's or not?
I have had 5.0 Mustangs, 2.3L Turbocoupes and all had a procedure to set the base idle. This involved starting the car with the IAC disconnected and setting the base idle to 400 or 500 RPM. After that, you shut the car off (this is all done after warm up BTW), and cut it back on to verify the base idle setting. Once you reach the base idle, you shut the car off and hook the IAC back up. The computer would then relearn the idle settings and should idle correctly.
Can any verify whether this is true or not? There is a reason why the Throttle body has that adjustment screw on it. Does anyone have a factory Ford manual with this info?
Thanks
Phil
