2 Check spark plug and spark of misfiring cylinder.
PREPARATION:
(a) Remove the ignition coil (See page IG±7).
(b) Remove the spark plug.
CHECK:
(a) Check spark plug type.
(b) Check for carbon deposits on electrode.
(c) Check electrode gap.
OK:
(a) Twin ground electrodes type.
Recommended spark plug:
ND PK20TR11
NGK BKR6EKPB±11
(b) No large carbon deposit present.
Not wet with gasoline or oil.
(c) Electrode gap:
Standerd: 1.0 ± 1.1 mm (0.03937 ± 0.043 in.).
Maximum: 1.3 mm (0.051 in.).
PREPARATION:
(a) Install the spark plug to the ignition coil, and connect the
ignition coil the connector.
(b) Disconnect injector connector.
(c) Hold the end about 12.5 mm (0.5 in.) from the ground.
CHECK:
Check if spark occurs while engine is being cranked.
NOTICE:
To prevent excess fuel being injected from the
injectors during this test, don't crank the engine for more
than 5 ~ 10 sec. at a time.
OK:
Spark jumps across electrode gap.
NG Replace or check ignition system
(See page IG±1).
OK

(c) Replace the ATF.
(1) Remove the drain plug and drain the fluid.
(2) Reinstall the drain plug securely.
(3) With the engine OFF add new fluid through the oil
filler pipe.
Fluid type: ATF D±II or DEXRON®III (DEXRON®II)
Capacity: 2.5 liters (2.6 US qts, 2.1 Imp. qts)
(4) Start the engine and shift the shift lever into all posi-
tions from P to L position and then shift into P posi-
tion.
(5) With the engine idling, check the fluid level. Add
fluid up to the COOL level on the dipstick.
(6) Check the fluid level is at the normal operating tem-
perature, 70 ± 80 °C (158 ± 176 °F), and add as
necessary.
NOTICE:
Do not overfill.
(d) Check the fluid leaks.
Check for leaks in the transaxle.
If there are leaks, it is necessary to repair or replace O±rings,
gasket, oil seals, plugs or other parts.
(e) Inspect and adjust the throttle cable.
(1) Check that the accelerator pedal is fully released.
(2) Check that the inner cable is not slack.
(3) Measure the distance between the outer cable end
and stopper on the cable.
Standard distance: 0 ± 1 mm (0 ± 0.04 in.)
If the distance is not standard, adjust the cable by the adjusting
nuts.
