SPARK PLUG SERVICE
When replacing the spark plug and coil cables, route the cables correctly and secure them in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise, cross ignition of the spark plugs or short circuit the cables to ground.

CAUTION: Do not attempt to adjust the gap of a platinum plug. Cleaning of the platinum plug may damage the platinum tip.
