Idle Speed

  1. Apply parking brake.
  2. Warm up the engine to normal operating temperature.
  3. Turn OFF all electrical loads.
  4. Connect inductive tachometer to number one (1) spark plug wire or connect tachometer pickup lead to terminal `O' in the data link connector (DLC). In case of using scan tool connect Hi-scan pro to the DLC.
    NOTE: The base idle speed is not adjustable. The idle speed is automatically controlled by the engine control module. Incorrect idle speed indicates a potential problem with the IAC system or an intake manifold leak.
  5. Check that idle speed is within specified range.

    Idle speed (transaxle in "NEUTRAL"): 750 +/- 50 RPM

    NOTE: This is a "wasted spark" ignition system, some tachometers will indicate twice the actual engine speed.
  6. Disconnect tachometer from DLC or spark plug wire.
  7. Turn off engine.
