## Idle Speed Inspection

NOTE:

- Leave the Idle Air Control (IAC) valve connected.
- Before checking the idle speed, check these items:
  - The Malfunction Indicator Lamp (MIL) has not been reported on.
  - Ignition timing
  - Spark plugs
  - Air cleaner
  - PCV system

1. | Disconnect the Evaporative Emission (EVAP) canister purge valve 2P connector.

2. | Connect a tachometer (A) to the test tachometer connector (B), or the HDS to the Data Link Connector (DLC) (C) located under the driver's side of the dashboard.

3. | Start the engine. Hold the engine at 3,000 rpm (min-1) with no load (in Park or neutral) until the radiator fan comes on, then let it idle.

4. | Check the idle speed with no-load conditions: headlights, blower fan, rear defogger, radiator fan, and air conditioner are not operating.
Idle speed should be:
750±50 rpm (min-1) (in nutral position)

5. | Idle the engine for 1 minute with heater fan switch on HI and air conditioner on, then check the idle speed.
Idle speed should be:
850±50 rpm (min-1) (in nutral position)
NOTE: If the idle speed is not within specification, see the Symptom Troubleshooting Index.

6. | Reconnect the EVAP canister purge valve 2P connector. NOTE: You can use the HDS to inspect idle speed.
