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. If manual and decal differ, always use decal specifications.
- EPA high altitude emission standards apply to vehicles sold in certain areas outside California which have an elevation above 4,000 feet.
- When performing tune-up on vehicles equipped with catalytic converters, do not allow or create an engine misfire in one or more cylinders for an extended period of time. Damage to converter may occur due to loading converter with unburned air/fuel mixture.
