Get your hands on a laser thermometer ($40 at harbor freight) and give this test a whirl: https://mustangforums.com/forum/5-0l...l.html#2355308
Also try swapping the MAF out if the 87 has been converted.

I had a similar issue before. First i replaced my Idle air control valve. the one that hangs off the side of the Throttle body, that didnt help and i kept having issues. weird backfires and things. it turned out to be a plug on the ground cable cut and spliced it and it ran fine from then on.
