Tune-Up Notes

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

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

When connecting a tachometer to Dura-Spark ignition coil, install the alligator clip on tachometer into the "DEC" (Tach Testing) cavity. If any spark plug wire is disconnected with this system, connection must be first greased with silicone grease before it is reattached.

Due to production changes, always refer to Engine Tune-Up Decal in engine compartment before attempting tune-up. In the event of conflict between specifications given in this manual and decal specifications, use decal specifications.
