Old Land Patrol 100 Idle speed is too high to get off.

The old Land Patrol 100 can't compete at idle speed. Reasons: throttle failure, idle speed control valve failure, sensor failure.

1, throttle failure. Too dirty throttle will lead to wrong throttle opening, lower throttle sensitivity, and the throttle can not be closed normally at idle speed, resulting in abnormal idle speed. In addition, the throttle failure will also affect the engine's power, acceleration performance and fuel consumption, and even lead to difficulties in starting in serious cases.

2. Idle speed control valve is faulty. The failure of idle valve will make the idle speed unable to be adjusted correctly, which will cause problems such as unstable idle speed and difficult cold start. In severe cases, there will even be no idle speed, and the engine will turn off as soon as the throttle is released.

3. Sensor failure. Sensor failure, computer error, or computer failure, engine idling is abnormal.
