(d) Remove the high±tension cords set.
(1) Disconnect the clamp from the emission control
valve set.
(2) Remove the high±tension cords set in indicated
direction.
(e) Using an ohmmeter, measure the resistance.
Maximum resistance: 25 kW per cord
If the resistance is greater than maximum, check the terminals.
If necessary, replace the high±tension cord.
(f) Install the high±tension cords set.

(g) Connect the high±tension cords to the ignition coils.
(1) Assemble the holder and grommet.
(2) Align the spline of the ignition coil with the spline of
the holder, and push in the cord.
NOTICE:
Check that the holder is correctly installed to the grommet
and ignition coil as shown in the illustration.
(3) Check that the lock claw of the holder is engaged by
lightly pulling the holder.
(h) Connect the high±tension cords to the spark plugs.
(i) Install the V±bank cover.
3. INSPECT SPARK PLUGS
NOTICE:

Never use a wire brush for cleaning.

Never attempt to adjust the electrode gap on a used
spark plug.

Spark plugs should be replaced every 100,000 km
(60,000 miles).
(a) Remove the high±tension cords set. (See step 2)
(b) Remove the ignition coils.
(c) Inspect the electrode.
Using a megger (insulation resistance meter), measure
the insulation resistance.
Standard correct insulation resistance:
10 MW or more
If the resistance is less than specified, proceed to step (e).
HINT:
If a megger is not available, the following simple method of in-
spection provides fairly accurate results.
(d) Simple Method:
(1) Quickly race the engine to 4,000 rpm 5 times.
(2) Remove the spark plug. (See step (e))
(3) Visually check the spark plug.
If the electrode is dry ... OK
If the electrode is wet ... Proceed to step (f)
(4) Install the spark plug. (See step (i))

(e) Using a 16 mm plug wrench, remove the 6 spark plugs
from the RH and LH cylinder heads.
(f) Check the spark plug for thread damage and insulator
damage.
If abnormal, replace the spark plug.
Recommended spark plug:
DENSO madePK20TR11
NGK madeBKR6EKPB11
(g) Inspect the electrode gaps.
Maximum electrode gap for used spark plug:
1.3 mm (0.051 in.)
If the gap is greater than maximum, replace the spark plug.
Correct electrode gap for new spark plug:
1.1 mm (0.043 in.)
NOTICE:
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 the used plug.
(h) Clean the spark plugs.
If the electrode has traces of wet carbon, allow it to dry and then
clean with a spark plug cleaner.
Air pressure: Below 588 kPa (6 kgf/cm
2, 85 psi)
Duration: 20 seconds or less
HINT:
If there are traces of oil, remove it with gasoline before using the
spark plug cleaner.
(i) Using a 16 mm plug wrench, install the 6 spark plugs to
the RH and LH cylinder heads.
Torque: 18 N´m (180 kgf´cm, 13 ft´lbf)
(j) Install the ignition coils.
(k) Install the high±tension cords set. (See step 2)
4. INSPECT IGNITION COILS
(a) Disconnect the high±tension cords from the ignition coils.
(b) Disconnect the ignition coil connectors.

(e) Connect the ignition coil connectors.
(f) Connect the high±tension cords to the ignition coils.
5. INSPECT CAMSHAFT POSITION SENSOR
(a) Disconnect the camshaft position sensor connector.
(b) Using an ohmmeter, measure the resistance between ter-
minals.
Resistance:
