(c) Using a spark plug cleaner or wire brush, clean the spark
plug.
(d) Check the spark plug for electrode wear, threads damage
and insulator damage.
If abnormal, replace the plugs.
Recommended spark plugs:
ND: K16R−U
NGK: BKR5EYA
(e) Carefully bend the outer electrode to obtain the correct
electrode gap.
Correct electrode gap: 0.8 mm (0.031 in.)
(f) Using a 16 mm plug wrench, install the spark plug.
Torque:
20 N·m (200 kgf·cm, 14 ft·lbf)
(g) Connect the high−tension cords to the spark plugs.
NOTICE:
Check that the holder is correctly installed to the grommet
and ignition coil as shown in the illustration.
(h) Check that the lock claw of the holder is engaged by lightly
pulling the holder.
4. INSPECT IGNITION COIL
NOTICE:
”Cold” and ”Hot” in these sentences express the tempera-
ture of the coils them selves.
”Cold” is from − 10 °C (14 °F) to 50 °C (104 °F) and ”Hot”
is from 50 °C (104 °F) to 100 °C (212 °F)
(a) Disconnect the distributor connctor.
(b) Remove the distributor cap.
(c) Remove the rotor.
(d) Remove the ignition coil dust cover.

2. INSPECT HIGH−TENSION CORDS
(a) Remove the air cleaner cap and MAF meter assembly.
(b) Disconnect the high−tension cords from the spark plugs.
Disconnect the high−tension cords at the rubber boot.
DO NOT pull on the cords.
NOTICE:
Pulling on or bending the cords may damage the conduc-
tor inside.
(c) Disconnect the high−tension cords from the ignition coils.
(1) Using a screwdriver, lift up the lock claw and discon-
nect the holder from the ignition coils.
(2) Disconnect the high−tension cord at the grommet.
DO NOT pull on the cord.
NOTICE:
Pulling on or bending the cords may damage the conductor
inside.Do not wipe any of the oil from the grommet after the
high−tension cord is disconnected.
(d) Inspect the high−tension cord resistance.
Using an ohmmeter, measure the resistance.
Maximum resistance:
25 kΩ per cord
If the resistance is greater than maximum, check the terminals.
If necessary, replace the high−tension cord.

(e) Reconnect the high−tension cords to 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 distributor cap as shown in the illustration.
(3) Check that the lock claw of the holder is engaged by
lightly pulling the holder.
(f) Reconnect the high−tension cords to spark plugs.
(g) Reinstall the air cleaner cap and MAF meter assembly.

3. INSPECT SPARK PLUGS
(a) Remove the high−tension cords and ignition coils.
(b) Remove the spark plugs.
Using a 16 mm plug wrench, remove the 6 spark plugs
from the RH and LH cylinder heads.
(c) 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.
(d) Visually inspect the spark plugs.
Check the spark plug for thread damage and insulator
damage.
If abnormal, replace the spark plug.
Recommended spark plug:
ND: K16TR11
NGK: BKR5EKB−11
(e) Adjust the electrode gap.
Carefully bend the outer electrode to obtain the correct
electrode gap.
Correct electrode gap:
1.1 mm (0.043 in.)
(f) Reinstall the spark plugs.
Torque:18 N·m (180 kgf·cm, 13 ft·lbf)
(g) Reinstall the ignition coils. (See page IG−8)
(h) Reconnect the high−tension cords.
4. INSPECT IGNITION COIL
(a) Remove the air cleaner cap and MAF meter assembly.
(b) Disconnect the high−tension cords from the ignition coils.
(c) Disconnect the ignition coil connectors.
