ERRATIC IDLE AND ENGINE MISFIRING UNDER LOAD - 1983-1984 BONNEVILLE AND GRAND PRIX
Some 1983 and 1984 Bonneville and Grand Prix models with V6 and V8 engines may experience an erratic engine idle and misfire under load. In
addition to these conditions, a radio static ignition noise on V8 equipped models may be present.
These conditions may be due to distributor cap carbon tracking. Silicone grease deposits on the distributor terminals may break down and cause deposits
of carbon to accumulate inside the cap.
Repairs can be performed by cleaning the rotor contacts inside the distributor cap and removing any silicone grease and carbon deposits. On severely
pitted distributor cap contacts, replacement of the cap is recommended.
