Idle Speed Adjustment
4. Remove the waterproof female connector from the ignition timing adjustment connector.
5. Use a jumper wire to ground the ignition timing adjustment terminal.
6. Start the engine and run at idle.
7. Check the basic idle speed.
-
Standard value: 700 + 50 RPM.
NOTES:
-
The engine speed may be 20 to 100 RPM lower than indicated above for a new vehicle (drive approximately 500 km (300 miles) or less) but
no adjustment is necessary.
-
If the engine stalls or the RPM is low even though the vehicle has been driven approximately 500 km (300 miles) or more it is probable that
deposits are adhered to the throttle valve so clean it.
Idle Speed Adjustment
8. If not within the standard value range turn the engine speed adjusting screw to make the necessary adjustment.
NOTE: If the idling speed is higher than the standard value range even when the engine speed adjusting screw is fully closed check whether or
not there is any indication that the fixed SAS has been moved. If there is an indication that it has been moved adjust the fixed SAS. If there are no
indications that it has been moved it is possible that there is leakage as a result of deterioration of the Fast Idle Air Valve (FIAV) and if so the
throttle body should be replaced.
