2. Install the tachometer and timing light.
3. Run the engine and let it idle.
4. Check the basic ignition timing.
Basic ignition timing : 10° ± 5° BTDC at idle
5. To check idle speed, be sure stop grounding the ignition timing adjustment terminal.
6. Let the engine idle for 2 minutes.
7. Check the idle speed.
Idle speed: 700 ± 100 rpm
NOTE:
- The engine speed on a new vehicle driven less than 500 km (300 miles) may be 20 to 100 rpm lower than specification. But no adjustment is necessary because Idle Speed Control System adjusts automatically
- If the engine stalls or the engine speed is low after the vehicle has been driven a distance of 500 km (300 miles) or more, It's possible there may be residue on the throttle plate. Refer to the throttle body cleaning.
