Affects Chevrolet Corvette, Monte Carlo, Camaro · 1984–1985 — about 4K vehicles.

The hazard

Certain Camaro, Firebird, Monte Carlo and Grand Prix equipped with a 5.0L engine, and 5.7L Corvettes. High ignition coil temperatures combined with the stress of higher voltage may break down the coating of the high output ignition coil secondary windings. Declining ignition voltage may lead to engine misfire, hesitation sags or no re-start. Depending on road condition, this could result in a significant safety hazard. Correction: High output ignition coil will be replace, spark plug gap will be revised and a spark plug gap revision label will be installed.
