NOTICE:
”Cold” and ”Hot” in the following sentences express the
temperature of the coils themselves. ”Cold” is from −10°C
(14°F) to 50°C (122°F) and ”Hot” is from 50°C (122°F)

1. INSPECT SPARK TEST
Check that the spark occurs.
(1) Disconnect the high−tension cords from the spark
plug.
(2) Remove the spark plug.
(3) Install the spark plug to each high−tension cord.
(4) Ground the spark plug.
(5) Check if spark occurs while engine is being
cranked.
NOTICE:
To prevent excess fuel being injected from the injectors
during this test, do not crank the engine for more 1 − 2 se-
conds at a time.
If the spark does not occur, perform the test as follows:

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.

(d) Inspect the primary coil resistance.
Using an ohmmeter, measure the resistance between the
positive (+) and negative (−) terminals.
Primary coil resistance :
Cold: 0.67 − 1.05 Ω
Hot: 0.85 − 1.23 Ω
If the resistance is not as specified, replace the ignition coil.
(e) Remove the ignition coils.
(f) Inspect the secondary coil resistance.
Using an ohmmeter, measure the resistance between the
positive (+) and high−tension terminals.
Secondary coil resistance:
Cold: 9.3 − 16.0 kΩ
Hot: 11.7−18.8 kΩ
If the resistance is not as specified, replace the ignition coil.
(g) Reinstall the ignition coils.
(h) Reconnect the ignition coil connectors and high−tension
cors.
(i) Reinstall the air cleaner cap and MAF meter assembly.
5. INSPECTION CAMSHAFT POSITION SENSOR
(a) Disconnect the camshaft position sensor connectors.
