What does throttling organic carbon affect? Carbon deposition is unclear, okay?

Nowadays, 4s stores are all required to generate income, and they will provide expenses other than maintenance, such as cleaning the throttle, cleaning the carbon deposit and cleaning the oil circuit. Since there is nothing wrong with your car when it is idling and accelerating, it is unnecessary to spend this penny. However, if you feel weak in acceleration, or it is difficult to start the car in cold weather, it may be a carbon deposit problem.
