5. ADJ UST ELECTRODE GAP
Carefully bend the outer electrode to obtain the correct
electrode gap.
Correct electrode gap: 0.8 mm (0.031 in.)
6. INSTALL SPARK PLUGS
Using SST, install the spark plug.
SST 09155-16100
Torque: 180 kg-cm (13 ft-lb, 18 N·m}
7. RECONNECT HIGH-TENSION CORDS TO SPARK

INSPECTION OF IGNITION COIL
1. IN:SPECT PRIMARY COIL RESISTANCE
2.
Using an ohmmeter. measure the resistance between the
positive (+) and negative (-}terminal.
Primary coif resistance (Cold):
2WD 1.28 - 1.56 kO
If the resistance is not as specified. replace the ignition
coil.
INSPECT SECONDARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between the
positive (+) terminal and high-tension terminal.
Secondary coil resistance: (Cold)
2WD 10.4 - 14.0 kO
If the resistance is not as specified, replace the ignition
coil.
DISTRIBUTOR
1. INSPECT AIR GAP
Using a feeler gauge, measure the gap between the signal
rotor and pickup coil projection.
Air gap: 0.2 mm (0.008 in.) or more
If the air gap is not as specified, replace the llA housing .
