How much does it usually cost to clean the throttle and nozzle?

Cleaning the carbon deposits on the throttle and fuel injectors is probably around 300 yuan, and the cost varies from place to place. Dirty throttle and injector will lead to power loss and unstable idle speed, which will seriously lead to engine fault lights, so it is necessary for us to clean throttle and injector regularly. 1. The throttle valve is a controllable valve that controls air to enter the engine. There are two kinds: traditional cable throttle and electronic throttle. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, thus burning to do work; 2. It is called the throat of an automobile engine, which is connected with the air filter and the engine block. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle. Whether the throttle should be removed for cleaning is also the focus of discussion among car owners; 3. The injector itself is a normally closed valve. When the electromagnetic coil is energized, the suction force is generated, the needle valve is sucked up, the nozzle hole is opened, and the fuel is ejected at a high speed through the annular gap between the shaft pin at the head of the needle valve and the nozzle hole, forming a mist, which is beneficial to full combustion.
