that could be any number of issues. I'll bet you have a fugged up injector. Get thee to a mechanic with a grand in hand.

Hi everyone. New to the forum, but not Mustangs. I believe you need a new computer. A buddy of mine had the same problem on an 89 Mustang and after trying several different things (new IAC, TP sensor etc, etc) he finally tried a new computer. Fixed the problem.
