How much is it for Buick Lang Wei to clean the throttle once (does Lang Wei need a computer after cleaning the throttle)?

The price of cleaning the throttle valve in Buick Lang Wei is around 100 yuan, and it will be more expensive to clean it in a professional 4s shop. It is not difficult to clean the throttle technically, but it must be handled with professional tools and detergents. Before cleaning the throttle, it is necessary to check the working state of the vehicle engine with a vehicle scan tool to confirm whether it needs cleaning. Turn off the engine, remove the accelerator and clean it with detergent. It should be noted that the metal on the accelerator surface of many automobile brands now has a special coating, so it is necessary to control the cleaning efforts to prevent the coating from being damaged. If the carbon deposit is serious, you can directly spray a proper amount of detergent on the throttle valve to allow the cleaning components to fully react with the carbon deposit before cleaning.

The throttle in Lang Wei is basically cleaned every 30,000 kilometers. However, it is not accurate to determine the interval of cleaning throttle valve in kilometers. Throttle scaling is mainly caused by oil vapor, followed by particles and moisture in the air. That is to say, if the throttle is used empty and the crankcase ventilation pipe is removed, the scaling speed will be much slower. The crankshaft is built in the crankcase, and the lower side is connected with the oil bottom. The working temperature of this part is about 100 ~ 180. When in use, oil will be heated and volatilized. The longer the use time, the higher the temperature and the stronger the volatilization. In addition, the compressed air of the cylinder will squeeze into the crankcase through the gap of the piston ring, so there must be a channel to let the gas out, otherwise the oil bottom will form positive pressure.
