- Inspect for proper ignition voltage output with the Spark Tester (J 26792).
- Remove the spark plugs and inspect for the following:
- Wet Plugs
- Cracks
- Wear
- Improper Gap
- Burned Electrodes
- Heavy Deposits
- An improper spark plug gap will cause a driveability problem. Gap the spark plugs using a wire gauge gap tool.
- Determine the cause of the fouling before replacing the spark plugs.
- Visually and physically inspect the secondary ignition for the following:
- Ignition wires arcing to ground.
- Ignition wires for proper routing.
- Soaking the secondary ignition system with water from a spray bottle may help locate damaged or deteriorated components. Look and listen for arcing or misfiring as you apply water.
- Inspect for loose ignition coil grounds.
