4. Remove the spark plug.

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:

D

Fuel mixture is too rich.

D

Oil in the combustion chamber.

D

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:

D

Fuel mixture is too lean.

D

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
type spark plug with the same physical dimensions as the
original equipment spark plug.

3. Check the gaskets for damage and replace if

necessary.

4. Measure the spark plug gap. The specification is 1.05

mm (0.040”).

5. Adjust the spark gap by bending the grounded

electrode.

014RX048

Installation Procedure

1. Tighten the spark plug to the 25 Nm (2.6 kg·m/18 lb ft).
2. Push the spark plug cable in until it snaps in.

3. Install spark plug cover onto valve cover and secure it

with four retaining bolts.

Spark Plug Cables

Spark Plug Cables

The cable contains a synthetic conductor which is easily
damaged. Never stretch or kink the cable. Disconnect the
cable from spark plug and the ignition coil.
The original equipment cables and the ignition coil are
marked to show correct location of the cables. If spark
plug cables or the ignition coil are replaced previously,
before cables are removed from the ignition coil, mark the
cables and the coil so they can be reconnected in the
same position.

014RX050

Inspection Procedure

NOTE: Never puncture the spark plug cable’s insulation
with a needle or the pointed end of a probe into the cable.
An increase in resistance would be created which would
cause the cable to become defective.

1. If the cable has broken or cracked insulation, it must

be replaced.

2. If the terminals are corroded or loose, the cable must

be replaced.

3. Check that the cable resistance does not exceed 10 k

W

 per foot.

EMISSIONS  Catalytic Converter

Catalytic Converter

Refer to Engine Exhaust.

Air Conditioning Relay

Removal Procedure

1. Remove the fuse and relay box cover at right side of

engine room.

2. Refer to the diagram on the cover to determine which

is the correct relay.

3. Insert small screwdriver or use thumb pressure to

release the retainer of the relay.
