Why does the double-row new car of Rongguang Xiaoka 1.5 have a high idle speed when shifting gears?

High idle speed is caused by throttle failure or sensor failure.

Too dirty throttle will lead to throttle opening error, throttle sensitivity will be reduced, and it may not be closed well at idle speed, resulting in abnormal idle speed; The failure of idle speed control valve will cause problems such as unstable idle speed and difficult cold start. If the sensor fails, the computer will make a mistake and the engine will be abnormal when idling.

Sensor failure. Sensor failure, computer error, or computer failure, engine idling is abnormal. The idle speed of this car is too high and it consumes a lot of fuel. It doesn't really matter much when it starts, because it can be controlled by the throttle. The simple thing is that when you practice changing positions, you don't need the throttle, and you can start directly by releasing the clutch. At this time, the idle car is fast and the idle car is slow. So if it is too small, it is easy for people who have just learned to drive to stall.
