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) to 100°C (212°F).
1. INSPECT IGNITOR AND SPARK TEST
Check that the spark occurs.
(1) Disconnect the high−tension cords from the spark plugs.
(2) Remove the spark plugs.
(3) Install the spark plugs to each high−tension cord.
(4) Ground the spark plug.
(5) Check if spark occurs while engine is being cranked.
NOTICE:
To prevent gasoline from being injected from injectors during this test, crank the engine for no more than 1
− 2 seconds at a time.
If the spark does not occur, perform the test as follows:

2. INSPECT HIGH−TENSION CORDS
(a) Disconnect the MAF meter connector and IAT sensor
connector.
(b) Loosen the hose clamp, disconnect the air cleaner hose
from the intake air connector.
(c) Remove the air cleaner cap and MAF meter assembly.
(d) Disconnect the air hose (for IAC) from the air connector.
(e) Remove the 2 bolts.
(f) Loosen the hose clamp, disconnect the intake air connec-
tor from the throttle body.
(g) Disconnect the high−tension cords from the spark plugs.
NOTICE:
Pulling on or bending the cords may damage the conductor in-
side.
(h) 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 distributor cap.
(2) Disconnect the high−tension cord at the grommet.
NOTICE:
Pulling on or bending the cords may damage the conduc-
tor inside.
Do not wipe any of the oil from the grommet after the high−
tension cord is disconnected.
