    Try another idle control unit and valve. Shouldn't cost you too much.

      Finally fixed it, ICV must have been the problem. Took it out, plugged the holes and she's cherry now. :up:

        It is super common for the IAC controller to crap out. it's located beside the DME above the glove box. If it is an 85 you can just give power and ground to the IAC valve and adjust the screw, if it's an 84 then you'll have to find a good controller, or put a restricter in the IAC inlet, and adjust the throttle stop screw to achieve a good idle.
