What are the signs that the throttle is broken?

The signs that the throttle valve of Pacific Auto Network is broken are: the engine idle speed is unstable, the high idle speed drops discontinuously, and it is difficult to start the engine, especially the cold start; Engine idle speed is unstable or no idle speed; Engine starting difficulty, etc.

Throttle is a control device to control the amount of air entering the engine. Connecting to the air filter and engine block is easy to produce carbon deposit. Whether the car is clean or not has a lot to do with whether it is sensitive to acceleration.

Valves have many functions, mainly in the following aspects: 1, to improve power by accelerating or decelerating; 2, through its self-regulation, correct the air intake function; 4. The function of controlling the operation of the engine assembly (the idle switch inside the engine is working); 5, control the flap, through the work of the sensor, control the size of the air intake, for the promotion of power; Dirty throttle is mostly caused by poor air quality and poor oil quality. Due to the negative pressure, the carbon deposit produced in the process of gasoline combustion will infect the throttle valve and make it not close well, thus increasing the intake air, causing signal transmission errors, resulting in high fuel consumption and engine idling jitter.
