Idle Speed
- Apply parking brake.
- Warm up the engine to normal operating temperature.
- Turn OFF all electrical loads.
- Connect inductive tachometer to number one (1) spark plug wire or connect tachometer pick-up lead to terminal number three (3) in the data link connector (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.
- 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. - Disconnect tachometer from DLC or spark plug wire.
- Turn off engine.
