Ignition Timing: Adjustments

1. Shift the transaxle to Park or Neutral, then make sure that the A/C and heater tan is in the Off position.
2. Connect an Inductive Timing Light, 059-00005 or equivalent to the number 1 spark plug wire.

4. Start engine and allow it to warm up to normal operating temperature.
5. Ground the black 1-pin STI self test connector located near the brake master cylinder.
6. Check the idle speed and adjust, if necessary.

10. Rotate the distributor until the timing marks are properly aligned.

13. Remove the jumper connecting the STI connector to ground.
14. Increase the engine rpm and check the timing marks to be sure that the ignition timing changes.
