Idle Speed: Adjustments

ADJUSTMENT CONDITIONS:
- Engine coolant temperature is 80 to 95°C (176 to 203°F).
- Engine lubricant temperature is over 80°C (176°F).
- Lights, electric cooling fan and all accessories are off.
- Transaxle is in neutral ["P" or N" range].
- Steering wheel is in straight ahead position.




IDLE SPEED ADJUSTMENT PROCEDURE
1. Loosen the accelerator cable.




2. Connect the tachometer.




3. Ground ignition timing adjusting connector terminal. Start the engine and let it idle. Check ignition timing and adjust if necessary.

Standard ignition timing BTDC 5° +/- 2°

4. Turn off the ignition switch and ground terminal 10 of data link connector. Alternatively, connect a scan tool to the data link connector.




5. Run the engine for more than 5 seconds at an engine speed of 2,000 to 3,000 rpm. Run the engine at idle for 2 minutes. Read the idle speed. If it is not within the specified limits, adjust the speed adjusting screw (SAS).

Base idle speed: 700 +/- 100 rpm

NOTE
1) If the engine is not sufficiently broken in, the engine speed is sometimes slightly below specification. In this case, adjustment is not necessary.
2) If the idle speed is higher than specified, even with the speed adjusting screw (SAS) fully closed, check whether the fixed SAS moving mark exists or not. If the switch has moved, the fixed SAS has been misadjusted.

6. Turn off the ignition switch and remove the ground from the ignition timing adjusting terminal and data link connector, or disconnect the scan tool.
7. Remove the tachometer and remove the ground terminal from the ignition timing adjusting connector.




8. Disconnect the battery terminal (-) for 15 seconds or more, and reconnect it.
9. Adjust the tension of the acceleration cable.
10. Restart the engine, and keep it idling for 5 minutes or more.
Adjustment

NOTE: Since the fixed SAS is adjusted at the factory, it is not necessary to adjust it in normal cases.
