I had the same probelm with my 1994 3.8 Taurus. Took it into Ford Dealership for repair. They first checked fuel pressure and it was ok.But they found a problem with the idle air control valve. Must be replaced can't be fixed or repaired(cost about $140 cdn for part)It sits on top of the engine Ford Part number cx-1854 (f68z-9f715-eb). take care I had the same probelm with my 1994 3.8 Taurus.
