Spark Plug: Testing and Inspection

INSPECT SPARK PLUG [19100P]

a. Inspect the electrode gap of the spark plug.

NOTE:
- Do not adjust the gap except when the plug is new (the mileage of the vehicle is less than 600 miles), because of the iridium plug.
- Do not damage the iridium tip. Plug type and electrode gap:




If the gap is greater than the maximum, consumption of the iridium tip might cause it. In this case, exchange the spark plug with a new one.

b. Clean the spark plug.

NOTE: Cleaning of the spark plug should not be done, because it might cause the iridium tip to be damaged. However, in case that the spark plug is remarkably dirty and cleaning is necessary, cleaning must be done in the shortest time (less than 20 seconds) in order to protect the electrode.
