The idle controller might be gone or the TPS. Or bad fuel.

The ISC on the throttle body could be the problem, when idling, remove the electric plug from it and se if it changes the idle at all. When remeved, the idle speed should considerable drop otherwise either that or the EEC is stuffed. Also, if you haven't already I would make sure you had some good spark plugs and leads on it, check the base timing and set the idle.
