What is cleaning the throttle?

Hello, clean the throttle. It is the throttle valve of the intake system of our engine that will produce a large amount of carbon deposits attached to the throttle valve during engine combustion, which will reduce the cross-sectional area of our intake valve and lead to the recent decrease of engine instability. So it is necessary to clean the throttle valve within a certain period. I hope it will be helpful to you and I hope it will be adopted.
