Idle Speed: Testing and Inspection

Before inspecting idle speed, make sure to the following.
- Lead wires and hoses of Electronic Fuel Injection and engine emission control systems are connected securely.
- After warming up engine, accelerator cable has some play, that is, it is not tight.
- Ignition timing is within specification.
- All of electrical loads except ignition are switched off.
- Air cleaner has been properly installed and is in good condition.
- Malfunction indicator lamp does not light when engine running. After above items are all confirmed, check idle speed as follows.
NOTE: Before starting engine, place transmission gear shift lever in "Neutral" (shift selector lever to "P" range for A/T model), and set parking brake and block drive wheels.
- Warm up engine to normal operating temperature.
- Set tachometer.
- Check idle speed with NC OFF.
If idle speed is not within specified range, check idle speed control system and any other system and parts which might affect idle speed.

Engine idle speed: 850±50 r/min

NOTE: Idle speed is not adjustable manually. If it is out of its specified range, there is a faulty condition somewhere. Check each of related systems and parts.
