Warning: The voltages produced by the contactless ignition system are significantly higher than those produced by a conventional system. Use extreme caution when working on the system with the ignition on. People with implanted cardiac pacemakers should not touch ignition system circuits, components, or test equipment.
1. Before checking the ignition timing, clean the timing marks. On the crankshaft pulley, the timing mark is indicated by a V-notch on the inside. On the timing chain cover, the timing marks are indicated by graduated strokes (photo). Using white paint, mark the V-notch on the pulley and the corresponding stroke on the timing chain cover (for the correct injection timing, see Specifications).
2. Start the engine and allow it to warm up to normal operating temperature, making sure the idle speed is correct, then turn off the engine and connect the timing light according to the manufacturer's instructions. Disconnect the vacuum line from the distributor, temporarily plug it.
3. Start the engine and aim the strobe light at the timing marks: the painted marks should be clearly visible and appear to be stationary. Make sure that the mark on the pulley is aligned with the correct mark on the drive chain cover or that its deviation is within the permissible limits.
4. If adjustment is necessary, loosen the distributor adjustment bolt, then rotate the housing until the timing marks align. Tighten the bolt and recheck the ignition timing.
5. If you now increase the engine speed, the automatic advance mechanism will cause the mark on the pulley to move away from the mark on the drive chain cover; if this is not the case, check the mechanism for proper operation.
6. Connect the vacuum tube; the ignition timing angle will change slightly. If the angle does not change, the distributor vacuum block may be defective.
7. When the adjustment is complete, turn off the engine and disconnect the strobe light.
