The
ignition timing cannot be adjusted. The distributor may need adjusting to prevent crossfire. To insure proper alignment of the distributor, perform the following:
- With the ignition OFF, install a scan tool to the DLC.
- Start the engine and bring to normal operating temperature. IMPORTANT: Cam Retard Offset reading will not be accurate below 1000 RPM.
- Increase engine speed to 1000 RPM.
- Monitor the Cam Retard Offset.
- If the Cam Retard indicates a value of 0°+/-2°, the distributor is properly adjusted.
- If the Cam Retard does not indicate 0°+/-2°, the distributor must be adjusted.

- Rotate the distributor as follows:
4.1. To compensate for a negative reading, rotate the distributor in the counterclockwise direction. 4.2. To compensate for a positive reading, rotate the distributor in the clockwise direction.
- Repeat step 4 until 0°+/-2°, is obtained.
- Turn the ignition OFF.
