Idle Speed: Testing and Inspection
IDLE SPEED CHECK PROCEDURE
CAUTION: An improper throttle valve opening will increase exhaust gas temperature at deceleration, reducing catalyst life and performance. It also has
an effect on fuel consumption and engine braking.
Checking conditions
-
Engine coolant temperature is 80 to 95°C (176 to 203°F).
-
Engine lubricant temperature is over 80°C (176°F).
-
Lights, electric cooling fan and all accessories are off.
-
Transaxle is in neutral ["P" or "N" range].
-
Steering wheel is in straight ahead position.
1. Install the tachometer and timing light.
2. Run the engine at curb idle speed.
3. Check the basic ignition timing and adjust if necessary.
4. Run the engine for more than 5 seconds at 2,000 to 3,000 rpm.
5. Run the engine at idle for 2 minutes.
6. Read the idle speed. If it is not within the specified value, check the idle speed control system
Curb idle: rpm 700 ± 100 rpm
NOTE: Idle speed adjustment is usually unnecessary, since the idle speed control motor adjusts the idle speed.
