If it stalls when you stop, then you probably have one of 2 things:
1. a bad turbo bypass valve. Find the vacuum hose that goes from the throttle body to the device under the distributor. Pull the end off the throttle body and suck on it. If it doesn't hold vacuum, the turbo bypass valve has a hole in the diaphragm and you need to replace it.
2. a bad dashpot. The dashpot is a little flying saucer-shaped thing in front of the throttle bellcrank. It is supposed to keep the throttle from slamming shut - when the tab on the bellcrank hits the post on the dashpot, it should take 6 or so seconds to fully close. Dashpots usually have a lifespan of about 10 years or so.
For the rest of your idle problem, have you changed vacuum hoses and the rubber bushings that hold vacuum nipples into the intake manifold and valve cover or cleande the AIC valve?
