You should inspect the spark plugs periodically for carbon deposits.
When carbon accumulates on the spark plug, a strong spark will
not be produced. Remove carbon deposits using a spark plug cleaner.
Spark Plug Replacement :
1. Clean up any dirt or oil that is collected around the spark plug
caps.
2. Pull out the spark plug cables by gripping at the connector.
3. Remove the spark plug with the help of a special socket.
4. Check and adjust the gap, it should be 0.7 mm to 0.8 mm.
5. Replace the spark plug if the gap is more than 1.2 mm.
6. Fix the spark plug and tighten it to the torque of 25 Nm (dry).
7. Fit the spark plug cable, until a 'click' sound is heard. Repeat
the procedure for the other spark plugs.
NOTICE
Tighten the spark plug carefully. Overtightening can damage the
threads in the cylinder head. A loose spark plug or loose spark
plug cable can affect combustion and cause damage to engine
and catalytic converter.
