Tune-Up Notes

NOTE: When performing tune-up procedures described in this article, the following notes and precautions must be followed.

Due to late changes and corrections, always refer to Engine, Tune-Up Decal in engine compartment, before tune-up procedures are attempted. In the event manual specifications and decal specifications are different, always use specifications on Engine Tune-Up Decal.

Before making a compression check or cranking engine with a remote starter switch, disconnect ignition wire at distributor.

Do not remove ignition wires while engine is running. Ignition voltage is extremely high and can cause harmful electrical shock.

If the Dura-Spark 2-piece distributor cap must be removed, first remove top portion, then rotor, then bottom portion. If any spark plug wire is removed, connection must first be coated with silicone grease before it is reconnected.

When performing tune-up on vehicles equipped with catalytic converters, do not allow or create a condition of engine misfire in more than one cylinder for an extended period of time. Damage to converter may occur due to loading converter with unburned air/fuel mixture.
