How much is it for Fox to clean the throttle?

If it's 4S, it's one or two hundred. Throttle cleaning is mainly labor cost, and the material cost is not very high. We clean for free.

How often is the throttle valve cleaned?

The correct way: If there are no abnormal phenomena such as car shaking, there is no need to clean it. Generally, the cleaning cycle of throttle valve is about 20,000 ~ 30,000 kilometers.

But it also depends on the condition of the car and driving habits. If the road conditions are not good during use or you often drive at a low speed, you need to replace it in advance.

Dirty throttle and fuel injector will lead to weak acceleration, loud noise, high fuel consumption, car shake and so on. Therefore, it needs to be cleaned regularly, usually just after cleaning the throttle and nozzle. Because the oil circuit is smoother than before, it will be more expensive to use temporarily. This is the adjustment of the driving computer through signal feedback, and then it will gradually return to the same fuel consumption. Therefore, if the gasoline valve and nozzle are cleaned frequently, it will easily lead to high fuel consumption and unstable idle speed of the vehicle, so if there are no abnormal phenomena such as jitter, there is no need to clean the vehicle.

In fact, it takes time or kilometers to do both cleaning. Generally, the cleaning cycle of throttle and nozzle is about 20,000 ~ 30,000 kilometers, but it also depends on the vehicle condition and driving habits. If the road conditions are not good during use or you often drive at a low speed, you need to replace it in advance.

Why is the throttle dirty?

Because of the ventilation function of engine crankcase and the function of activated carbon canister solenoid valve, a small amount of gasoline vapor will be brought to the throttle, and the oil and gasoline attached to the throttle will continue to attach to dust. How long the throttle will be dirty depends on the quality of air filter, engine oil, road conditions, temperature, engine working temperature, driving habits and so on. Dirty oil, long-term non-replacement of air filter and poor quality of air filter will aggravate the dirtiness of throttle valve. The throttle is equivalent to the "throat" of the engine.

Throttle is a controllable valve, which is used to control air to enter the engine. Above (or in front of) it is an air filter, and below it is an engine block. The position of the throttle valve is equivalent to the "throat" of the car. After the air enters the intake pipe, it needs to pass through the throttle valve, and then it is mixed with gasoline to form a combustible mixture, which participates in combustion and does work. Whether the idle speed of the car is stable and whether the acceleration is flexible is closely related to the cleanliness of the throttle.
