Ignition Timing
- Remove No. 1 ignition coil. Connect No. 1 ignition coil and No. 1 spark plug with a high tension wire (spark plug cable). Connect timing light to high tension wire. Start and warm engine to normal operating temperature (needle is in middle of coolant gauge).
- Run engine at 2000 RPM for 2 minutes. Perform self-diagnostic procedure and check for smooth engine operation. Increase engine speed to 2000 RPM two or three times, then allow engine to return to idle.
- Check ignition timing. If ignition timing is incorrect, loosen crank angle sensor mounting bolts. Adjust timing by turning crank angle sensor. With ignition timing correctly set, check idle speed and mixture. See IDLE SPEED & MIXTURE.
