Ignition Timing: Testing and Inspection

1. Check the idle speed, and adjust it if necessary (see Fuel and Emission System).
2. Pull out the service check connector 2P (GRN/BLU and RED wires) from the connector holder located under the dash on the front passenger side, then connect the SCS service connector (TIN O7PAZ - 0010100) to it.
3. Start the engine. Hold the engine at 3,000 rpm with no load (A/T in [N] or [P], M/T in neutral) until the radiator fan comes on, then let it idle.
4. Connect the timing light to the No. 1 ignition wire, then point the light toward the pointer on the timing belt cover.
5. Check the ignition timing in no load conditions: headlights, blower fan, rear window defogger, and air conditioner are not operating.

7. Tighten the distributor mounting bolts, and recheck the ignition timing.
8. Disconnect the SCS service connector from the service check connector.
