DISTRIBUTOR DIAGNOSIS/REPAIR REVISED PROCEDURE

VEHICLES AFFECTED: Late 1982 to 1984 Pontiac J2000 Sunbirds & Buick Skyhawks

The following procedure for the 1.8L OHC engine (VIN codes O and J) is being supplied for your information.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
