I don't know what the factory procedure is but i hamfist idle adjustments on old efi cars by introducing a big vacuum leak which will usually cause the idle speed motor to close all the way trying to bring the rpm down. Once it's closed i unplug it, stop the vacuum leak, and set the throttle plate to a low  idle (engine warm). Turn off, plug idle motor back in,  start back up. No guarantee that every 80s car is stupid enough to take that method, but some sure are!

Some old GM you could ground out one of the diagnostic terminals and it would cause the IAC motor to cycle completely then you just unplugged it and turned off the car.  If I remember when I get home I'll pop open a manual and see, what year?
