Spark plug cleaning or replacement will probably not resolve driveability complaints such as sags, poor fuel economy, etc. Diagnosis and repair
procedures described in the applicable "Driveability Test Procedure" should be followed for problem solving.

Spark plugs should only be cleaned or replaced when the symptoms justify this action. Conditions outlined in this bulletin and the test procedures
described in the appropriate Driveability Procedure Manual should preclude incorrect servicing of the spark plugs.
Cleaning or replacement of spark plugs for unrelated symptoms or conditions under warranty may be cause for claim denial or charge back.
