Possible vacuum leak. Check vacuum lines and replace if dry or cracked. Possible vacuum leak at intake manifold or base of throttle body(if equipped).

My 96 Lincoln Mark VIII had a slow idle and it was the idle control motor. I took it off, and was it a hard one to get to also. I cleaned it with some Mass Air sensor cleaner and it idles ok now. Ive been told that the same motor controls the idle, when its too fast also. Hope this helps. It is a hard little controller to get off. It is beside the throttle body and I had to take that off too. It wasn't bad to get off.
