Attention! On engines after 1990, the ignition timing is controlled automatically by the processor unit.
45.4 Marking on the pulley and scale for setting the ignition on 4-cylinder engines
45.2 Pulley mark and scale for ignition setting on 4-cylinder engines
1. When checking the angle of installation of the ignition, be guided by the data in the plate, reinforced on the inside of the hood.
2. On 4-cylinder engines, the ignition timing is checked by matching the mark on the crankshaft pulley with the division of the scale mounted above the pulley (photo). Label 0 corresponds to TDC.
3. Mark the mark on the pulley with light paint.
4. On the V6 engine, the ignition timing is checked by aligning the fixed pointer with the division on the scale printed on the damper pulley (photo).
5. Check idle speed, adjust if necessary. Connect the stroboscope according to the manufacturer's instructions.
6. Warm up the engine, stop and disconnect the devices that are indicated on the engine compartment plate for this engine
7. Attach a stroboscope according to the manufacturer's instructions.
8. Start the engine, press the gas pedal 2-3 times and switch to idle mode.
9. Point the strobe light at the crankshaft pulley. The illuminated mark should be opposite the corresponding division of the scale.
45.11 Setting the ignition
1. Increasing the lead angle; 2. Reducing the angle
10. If adjustment is necessary, loosen the distributor adjusting bolts.
11. To install 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 a stroboscope and check up turns of idling, if necessary adjust.
13. If ringing knocks are heard during the trip when the car is moving uphill or during acceleration, then reattach the stroboscope and reduce the lead angle by 1-2°.
