My sons 86 GT has a hunting idle when starting it cold. It revs up and down for about 1 to 2 minutes, not long at all, then it levels out and idles great. And there is no trouble restarting when the engine is warm. We just swapped this 2.8 in, replacing a bad 2.8, so this may be just a matter of getting it on the highway for about 30 minutes or so, and letting the computer do it's thing. Car is not titled yet, so I can't take it for a lengthy drive, but I'm trying to get out in front on this issue before that time comes. Thanks.

Make sure the throttle body is clean internally and take it for a drive. It'll have to relearn the idle parameters.

Thanks, will do. Kinda what I figured.

Update, after several days of just letting it run, and then taking it to the end of the street, and back, (can't go further, it's not registered) the idle is perfect!
