Component Inspection

Remove the spark plugs using the spark plug socket. (Refer to "REMOVAL ")
Check the spark plug for any damage.
Check the electrode. Measure the insulation resistance with an ohmmeter. If the resistance is less than the specified value, adjust the electrode gap.
Specification: 10 MΩ or more

Check the spark plug electrode gap. If the gap is greater than the maximum, replace the spark plug.

Specification: 0.8 - 0.9 mm (0.0314 - 0.0354 in.)

NOTE:

If adjusting the gap of a new spark plug, bend only the base of the ground electrode. Do not touch the tip. Never attempt to adjust the gap on a used plug.
