Spark plugs of the wrong size or incorrect heat range can cause

REMOVAL, INSPECTION AND REPLACEMENT
For good performance, the spark plug should have the correct gap
and be free of deposits.
1. Raise the engine hood, then disconnect the spark plug cap, and
remove any dirt from around the spark plug area.
2. Remove the spark plug.
3. Inspect the spark plug for excessively worn electrodes, chips or
cracks in the insulator, or excessive deposits. Replace the spark
plug if you have any doubts about its condition.
4. Measure the electrode
gap with a wire gap
gauge. Adjust the gap
to 0.7 - 0.8 mm (0.028
- 0.031 inch) by
bending the side
electrode with a
proper spark plug
tool.
0.7 - 0.8 mm
