IAC valve
After a two year battle with a Idle & Stalling problem, I finally replaced the IAC & Plug connector (both original & 16yrs old) and this cured my problem finallly. No more Low idle after restarting and stalling. One less headach. That valve was not worth taking apart and cleaning ( big time carbon build up) same for the plug connector.
Thanks to the guys that gave me the P/N's to track down these parts:hail:

Post the part numbers and your comments so that others can benefit from your experience (especially if it comes up in a search). Returning the favor is a much more satisfying way of thanking the people here. 
Glad you got your problem fixed.
