Tune-Up Notes

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

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 or disconnect feed wire in DIS systems.

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

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.
