How much does it cost to clean the throttle?

If it's a wired throttle, you can clean it yourself and buy a bucket of cleaning agent 6 yuan, but if it's an electronic throttle, it's not easy to match. Generally, the cleaning in roadside repair shops is around 100-200 (if it does not match, it may be around 50 yuan). 4S shop is expensive, a bucket of cleaning agent is about 100 yuan, and the labor cost is 65438.

The throttle valve is located at the front end of the engine intake manifold. When idling, air flows through the gap of the throttle at high speed (tens to hundreds of meters per second), generating negative pressure and gradually accumulating dust. In addition, crankcase blowby and engine oil vapor collected from the engine oil vapor recovery pipe are easily absorbed by the negative pressure at the gap of the car door, where the temperature is relatively low and it condenses to form sludge when it is cold. Congested road conditions and cold weather accelerated the formation of sludge. When there is more sludge, the intake air will generate eddy current and air resistance. The throttle is dirty, the idle throttle is not obedient, and the throttle cannot be stepped on. Excessive force is easy to be rough, which affects driving safety. Dirty throttle will lead to unstable idle speed, poor start, easy flameout and even failure to start halfway. Therefore, the throttle must be cleaned and maintained in time.
