  3. Idle Speed - Inspect
      1. Start the engine. Hold the engine speed at 3, 000 rpm without load (in P or N) until the radiator fan comes on, then let it idle.
    2. Check the idle speed under no load conditions: headlights, blower fan, radiator fan, audio system, and air conditioner off. Idle speed should be: 700 ± 50 rpm (in P or N) 
    3. Let the engine idle for 1 minute with high electric load (A/C on, temperature set to max cool, blower fan on high, headlights on high beam).Idle speed should be: 700 ± 50 rpm (in P or N) 
    NOTE: If the idle speed is not within specification, do the PCM idle learn procedure . If the idle speed is still not within specification, go to the symptom troubleshooting .
