Spark Plug Wires Not Operating Properly

INSPECTION PROCEDURE
1. Inspect the spark plug gap. Adjust as needed.
2. Inspect the spark plug wires for any obvious cuts, burns, or damage.
3. With the engine ON, inspect for any arcing to ground or other components.
4. Connect an ohmmeter to the end of each suspect wire. If the meter reads over 700 ohms, replace the wire.
