Idle Speed: Testing and Inspection
NOTE: Before setting the idle speed, check the following items:
-
The MIL has not been reported on.
-
Ignition timing
-
Spark plugs
-
Air cleaner
-
PCV system
1. Start the engine. Hold the engine at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on, then let it idle.
2. Connect a tachometer.
3. Disconnect the IAC valve 2P connector and the EVAP purge control solenoid valve 2P connector.
4. If the engine stalls, restart the engine with the accelerator pedal slightly depressed. Stabilize the rpm at 1,000, then slowly release the pedal until
the engine idles.
5. Check idling in no-load conditions: headlights, blower fan, rear defogger, radiator fan, and air conditioner are not operating.
Idle speed should be:
480 ± 50 rpm (in Park or neutral)
If necessary, adjust the idle speed, by turning the idle adjusting screw.
After adjusting the idle speed recheck the ignition timing. If it is out of spec, go back to step 4.
