Caution! The standard idle speed is set at the factory by adjusting the SAS setting bolt. Normally, no adjustment is required. If the setting has been mistakenly reset, set as shown below.
1. Connect the MUT II diagnostic tool to the diagnostic connector. The test terminal is grounded when the tool is connected.
2. Disconnect the sealed connector from the ignition.
3. Using a shunt cable, ground the ignition timing adjustment terminal (Figure 8.6).

4. Start the engine and let it idle.
5. Check the idle speed. Normal value: 750±50 rpm.
Caution! The engine idle speed may be 20-100 rpm lower for a new car. There is no need to reset them. If the engine stalls or the idle speed is too low, despite a mileage of more than 500 km, then there are deposits on the throttle valve that must be removed.
6. If the value does not correspond to the normal value, adjust it with the SAS adjusting bolt (Figure 8.7).

7. Turn off the ignition.
8. Disconnect the shunt cable from the terminal and connect the connector.
9. Disconnect the MUT II diagnostic tool.
10. Start the engine again and let it idle for 10 minutes. Make sure the idle speed is stable.
