014RX045

Inspection Procedure

1. Check the insulator for cracks. Replace the spark

plug if crack are present.

2. Check the electrode condition and replace the spark

plug if necessary.

014RX046

If the spark plug electrodes and insulators are fouled with
carbon or oil, the engine will not operate efficiently.
There are number of possible causes:

f

Fuel mixture is too rich.

f

Oil in the combustion chamber.

f

The spark plug gap is not set correctly.

If spark plug fouling is excessive, check the fuel and
electrical system for possible causes of trouble. If fuel and
electrical system are normal, install spark plug of a higher
heat range which have the same physical dimensions as
the original equipment spark plug.
The following symptoms are characteristics of spark
plugs that are running too hot:

f

Fuel mixture is too lean.

f

Heat range is incorrect.

014RX047

If vehicle usage does not conform to normal driving
conditions, a more suitable spark plug may be
substituted.
If fuel and electrical system are normal, in most cases of
this sort, the problem can be corrected by using a colder
