Attention! On engines after 1990, the ignition timing is adjusted automatically by the processor unit.
45.4 Mark on pulley and scale for setting ignition on 4-cylinder engines
45.2 Mark on pulley and scale for setting ignition on 4-cylinder engines
1. When checking the ignition timing angle, follow the data on the plate attached to the inside of the hood.
2. On 4-cylinder engines, the ignition timing is checked by aligning the mark on the crankshaft pulley with the division of the scale mounted above the pulley (photo). Mark 0 corresponds to TDC.
3. Mark the pulley with light paint.
4. On a V6 engine, the ignition timing scale is checked by aligning the fixed pointer with the division on the scale applied to the damper pulley (photo).
5. Check idle speed, adjust if necessary. Connect the stroboscope in accordance with the manufacturer's instructions.
6. Warm up the engine, stop and disconnect the instruments specified in the engine compartment label for this engine
7. Attach the strobe light according to the manufacturer's instructions.
8. Start the engine, press the gas pedal 2-3 times and switch to idle mode.
9. Direct the stroboscope light at the crankshaft pulley. The illuminated mark should be opposite the corresponding division on the scale.
45.11 Ignition setting
1. Increasing the advance angle; 2. Decreasing the angle
10. If adjustment is necessary, loosen the distributor adjusting bolts.
11. To set the ignition, turn the distributor housing until the mark aligns with the desired scale division (photo). Tighten the bolts and check the ignition setting again.
12. Disconnect the strobe light and check the idle speed, adjust if necessary.
13. If you hear loud knocking sounds when driving uphill or when accelerating, reconnect the stroboscope and reduce the advance angle by 1-2°.
