How much does Volvo xc60 cost to clean the throttle?

The price of cleaning the throttle of Volvo xc60 is generally around 400 yuan, and cleaning the throttle once is generally around 40,000 kilometers. Throttle is a controllable valve that controls air to enter the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It connects the air filter and the engine block, and is called the throat of the automobile engine. The throttle valve belongs to the intake area. At present, the piston of the engine works asynchronously. When the engine is turned off, the intake valves of some cylinders cannot be completely closed, and some unburned fuel will continue to vaporize and oxidize, producing some carbon deposits in the intake pipe, especially behind the throttle. On the one hand, these carbon deposits will block the idle channel and make the throttle stuck or out of its adjustment range. On the other hand, the wall of the intake pipe becomes rough, and the intake air will generate eddy currents in these rough places, which will affect the intake effect and the quality of the mixture, resulting in idling jitter, poor speed increase, and fuel consumption during flameout.
