Ignition Timing: Adjustments

IGNITION TIMING MEASUREMENT

CAUTION:
After warming-up, engine becomes very hot. Be careful not to burn yourself during measurement.

1) Warm-up the engine.
2) To check the ignition timing, connect a timing light to #1 cylinder spark plug cord, and illuminate the timing mark with the timing light.
3) Start the engine at idle speed and check the ignition timing.
If the timing is not correct, check the ignition control system.

Ignition timing [BTDC/rpm]:
140° ± 80°/700 (2200 cc MT vehicles)
200° ± 80°/700 (2200 cc AT vehicles)
150° ± 80°/700 (2500 cc models)

NOTE: To improve stability, ignition timing while engine is idling is also controlled. For this reason specified ignition timing range is increased somewhat, to +80.
