Ignition Timing

1. Check the condition of the engine (spark plugs, leaks in hoses, etc.).
2. Turn all electrical loads OFF.
3. Warm up the engine and run it for three minutes at 2,500-3,000 rpm in neutral or park.
4. Connect a tachometer and a timing light to engine.
5. Disconnect the vacuum hoses from the distributor vacuum control unit and plug the hoses.

Test Connector:

6. Ground the test connector (green: 1-pin) with a jumper wire.
7. Check that the idle speed is within specification.

Idle speed:
800 ± 20 rpm (M/T: neutral)
770 ±20 rpm (A/T: P range)


8. If the idle speed is not within specification, adjust it (refer to IDLE SPEED ADJUSTMENT).

Fig. 7 Timing Mark:

9. Check that the timing mark (YELLOW) on the crankshaft pulley and the mark on the timing belt cover are aligned.

Ignition timing: 11 ± 1 ° BTDC (at idle speed)

Fig. 8 Distributor Bolts:

10. If the ignition timing is not within specification, loosen the distributor lock bolts and rotate the distributor housing to adjust.
11. Tighten the distributor lock bolts to the specified torque.

Torque specification: 19-25 Nm (1.9-2.6 m-kg, 14-19ft-lb)

11. After adjusting the ignition timing, disconnect the jumper wire from the test connector and reconnect the vacuum hoses.
