The problem
THE SEALANT USED ON ROUGH ALUMINUM GOVERNOR HOUSING OF CERTAIN FUEL INJECTION PUMPS COULD PENETRATE THROUGH THE BUSHING WHEN THE ENGINE TEMPERATURE GETS UP TO OPERATING TEMPERATURE AND GETS BETWEEN THE THROTTLE SHAFT AND BUSHINGS CAUSE THE SHAFT TO BIND. CONSEQUENCE OF DEFECT: IF THE SHAFT BINDS IN THE BUSHING AND PREVENT THE THROTTLE SHAFT FROM RETURNING TO LOW IDLE POSITION WHEN ACCELERATOR IS RELEASED, IT MAY CAUSE LOSS OF VEHICLE CONTROL WHICH COULD RESULT IN A VEHICLE ACCIDENT.
What owners should do
REPLACE THROTTLE SHAFT BUSHINGS IN THE GOVERNOR HOUSING.
