CAMPAIGN:REPLACE COIL HIGH OUTPUT IGNITION
# THIS BULLETIN IS BEING REISSUED TO SUPERSEDE PRODUCT CAMPAIGN BULLETIN 85C22 DATED AUGUST, 1986. UPON RECEIPT OF THIS REISSUED BULLETIN 85C22(a), DESTROY 85C22.
General Motors has determined certain 1984-1985 Chevrolet Camaro and Monte Carlo models with 5.0L V8 engine and 1984-1985 Chevrolet Corvette models with 5.7L V8 engine may exhibit declining ignition voltage of the high output ignition coil.
High ignition coil temperatures combined with the stress of higher voltage may break down the epoxy coating of the high output ignition coil secondary windings. Declining ignition voltage may lead to engine misfire. hesitation, sags, or no re-start. Correction will consist of replacing the high output ignition coil and module, revising spark plug gap and installing a spark plug gap revision label.

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.
