Roewe 350 throttle is dirty, does it affect power?

Hello, the throttle is responsible for the amount of air intake, which is linked with the throttle. The deeper you step on the accelerator, the greater the throttle opening. The more air intake, the more gasoline is burned, and the speed goes up. Dirty throttle is related to oil and air quality. If you often add bad oil or air pollution, it is easy to cause dirty throttle. Too dirty throttle will cause insufficient power, the car will have food when it is moving, and the sound will increase when it is idling. Cleaning the accelerator is not a technical job. I clean it myself, and I can do it at 4s shop 100 or above.
