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 attempting tune-up procedures. In the event manual specifications and decal specifications are different, always use the specifications on the Engine Tune-Up Decal. 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 disconnected with this system, connection must be first coated with silicone grease before it is reattached. When connecting a tachometer to Dura Spark ignition coil, install the alligator clip on tachometer into the "DEC" (TACH TESTING) cavity of ignition coil. On vehicles equipped with catalytic converters, do not allow or create a condition of engine misfire in more than one cylinder for more than 30 seconds. Damage to converter may result due to loading of converter with unburned air/fuel mixture.
