TSB 88-16-16 Hazard Stumble

Publication Date: AUGUST 3, 1988

LIGHT TRUCK: 1987-88 F-SERIES, BRONCO

ISSUE: An engine miss or stumble when the headlamp hi-beams, hazard, stop or turn signals are turned "ON/OFF" may be caused by a voltage spike. A voltage spike may be induced into the EEC IV ignition system and read by the EEC IV processor as a PIP signal. This creates false timing information resulting in the miss or stumble. Vehicles that are used to pull trailers (electrical brake equipped) may have similar symptoms.

ACTION: To correct this, install a ground strap between the battery negative (-) terminal and the radiator support bracket using existing attaching hardware or a #10 sheet metal screw.
