2. Ensure the transmission is in PARK and set the parking brake.

9. Carefully remove the spark plug boots from the plugs

10. Remove both spark plugs for inspection with a 14mm deep well socket.

11. Inspect the electrodes for wear and carbon buildup. The spark plug should have a sharp outer edge with no rounding or erosion.
