I have a 1993 f150, v8, stalls otu when I stop at a stop sign, stop light or turn on the a/c. A/C line was disconnected, I reconnected it, worked for awhile then same issues. Could it be the IAC valve?? Please advise

Anyone have issues with a IAC on a 1993 F150?

The IAC can give problems like that. You can try cleaning it with carb cleaner and the MAF (with MAF cleaner). Check the throttle body too.
