So you must have the 351 cu. in., carbureted engine? Here is a link to the idle speed procedure. BTW, your VECI label (vehicle emission control information) under the hood somewhere, shows the correct idle speed number.

Well, it's just like Brad says then, all computer controlled. The idle motor is called I think a stepper motor. Find a cheap used one at an auto salvage yard. Use yours to match part numbers.

I am not sure how you set the idle the last time but the ford motor company uses and idle air speed motor control and when they get fouled and don't respond to commands then you get idle problems. They are a pain to deal with and not cheap.

The way I read it was you first unplug IAC then adjust the idle until the motor is barely running then stop the motor and disconnect the battery and wait 3 min then plug the IAC back in and connect the battery then start the motor but i don't know if there is something I missed??

Bill, you could possibly have a vacuum hose leak. With motor running, open your hood and listen carefully for a hissing sound. If you hear one, try to pinpoint where it's coming from.
