1. Warm up engine.
2. Confirm that throttle sensor idle switch is "ON."
3. Connect Test Mode connector (green connector).
4. Hook up timing light, start engine, set idle speed to specification and check timing.
5. If adjustment is needed, loosen 6mm distributor plate mounting bolts.
6. Turn distributor clockwise to advance timing and counterclockwise to retard timing.
7. When adjustment is complete, tighten bolts and recheck timing.
8. Turn off engine and disconnect Test Mode connector.
