searched.. no dice, weird idle issue

Hello, motor in question is an 88 L98

Car will idle at 900, then slow to 600-500 (sounds like a/c comes on) then goes back to 900.

IAC cause this? its not constant, but every 5-15 seconds will go from 900-5-600 and back.

Mine has the same issue, mine also sounds like it's "gulping" air when you blip the throttle.
