Why does the neutral speed of a car automatically increase?

The main problem lies in the position of the throttle. There are two or three wire plugs at the throttle. The plug is loose, resulting in poor contact. Suggest hard plug.

Extended data:

Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. It connects the air filter and the engine block, and is called the throat of the automobile engine.

How to clean and prevent should pay attention to:

1, which should be dismantled and cleaned;

2. Correct some mistakes in cleaning the throttle valve;

3. The fouling of the throttle is mainly engine oil vapor, followed by particles and moisture in the air. That is to say, using a qualified air filter and removing the crankcase ventilation pipe, the fouling speed of the throttle will be much slower.

The crankshaft is built in the crankcase, and the lower part is connected with the oil bottom. The working temperature of this part is about 100 ~ 180.
