    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"): 800 +/- 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.
