Did you have it tuned for the setup? A lot of things can cause that. Delayed idle adaptive, IAC motor, timing, throttle cracker. A good tune would fix it 99% of the time barring any mechanical issues.

Does the idle hang when car is in motion while out of gear/clutch in? Then right when you stop it drops down to normal? What kind of throttle body do you have? My car had the exact problem, if what stated, with the Fast 92 TB. I purchased a Nick Williams TB & it cured the problem. Due to the IAC passage being too small on the Fast. As chopper stated working on the tune may be able to cure it. Or maybe doing some porting on TB IAC port? Left you a link to thread related. Hope you get it figured.
