Spark Plug: Service Precautions
CAUTION:
-
Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will remain on the spark plug insulator and will cause plug
misfire.
-
Do not leave any one spark plug cable disconnected for longer than necessary during testing. This may cause possible heat damage to the catalytic
converter. Total test time must not exceed 10 minutes.
