it might be getting to much fuel.

1987,replace fuel filter,check fuel pressure at fuel rail,is this a throttle body clean with carb cleaner,carbon will build up around the butterfly or the flat piece in side causeing it not to close,if outer edge has a black ringe of build up on it that is the bigest prob,crank it,spray the heck out of it throttle it while cleaning,also clean replace mass air,you can get a can of mass air cleaner at any parts store.

Mine does the same thing. Ive replaced everything from the pump to the throttle body. One thing that did help was replacing the throttl positioning sensor.
