Chevy Malibu Hesitates on acceleration
If you have a Malibu hesitation on acceleration problem on your 2004-05 Chevrolet Malibu, you should read this GM service bulletin #04-06-03-010A. GM has issued the bulletin to address a Malibu hesitation on acceleration problem, drop in engine RPM, or idle stalling problem on 2004-05 Chevrolet Malibu with the 2.2L engine built before VIN 5F132617.
The Malibu hesitation on acceleration problem, drop in engine RPM, or idle stalling problem occurs during parking lot maneuvers or during deceleration. Occasionally it may stall at idle.
GM has isolated the problem to a voltage spike that occurs when the cooling fans kick on or off. The voltage spike disrupts the ignition signal from the crankshaft position sensor. Do NOT replace the crankshaft position sensor. Instead, GM has issued a wiring harness jumper
that contains a diode to prevent the spike from causing the IGN problem.
Purchase the harness, part #15242642. Then unplug the right fan open the clip holding the wiring conduit at the fan. Remove the clip from the jumper harness and connect it to the fan. Then connect the harness connector. Place the jumper in the existing clip and close the clip. Then route the wiring harness and connect to the fan motor support with a zip tie.
