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 A/C 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.
