Tune-Up Procedures - V8: Ignition: Distributor: Notes

All gasoline engines use a Delco-Remy, High Energy Ignition system. Module must be replaced as a unit. A liberal coat of silicone grease MUST be applied to the surface on which module will be mounted. Toronado models are equipped with Electronic Spark Timing (EST).

NOTE: Some 1977 Oldsmobile engines may stop running for no apparent reason, but upon restart, engine may appear to operate normally. Intermittent condition may be caused by broken Black ground wire at distributor module terminal.

NOTE: Some 1977 Oldsmobile Toronado models may experience erratic engine operation at 40-50 MPH. Excessive paint on EST distributor may be causing this condition. Remove Tan and Black wire terminals from distributor connector. Remove paint from terminals, if any.
