Idle Speed: Adjustments

NOTE:
(1) Before adjusting, check that the spark plugs, injectors, ISC motor, compression, etc. are normal.
(2) Clean the throttle body area.

Adjustment conditions:
- Engine coolant temperature is 80 to 95°C (176 to 205°F).
- Lights, electric cooling fan and all accessories are off.
- Transaxle is in neutral ["P" or "N" range for M/T vehicles].
- Steering wheel in straight forward position (vehicles with power steering).





1. Loosen the accelerator cable.
2. Connect the GST to the data link connector on the lower crash pad.
3. If the GST is not used, connect a tachometer, and ground the data link connector.





4. Ground the ignition timing adjustment terminal.
5. Run the engine for more than 5 seconds at an engine speed of 2,000 to 3,000 rpm.
6. Run the engine at idle for 2 minutes.
7. Check that the engine rpm is within the standard value.

Basic idle speed 750: 100 rpm

NOTE:
(1) 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.
(2) 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, a deposit on the throttle valve area is suspected.

8. If the basic idle speed is out of specification, adjust basic idle speed.
