Why can't Mazda clear the throttle?

The throttle valve is the air inlet of the engine. When the air flows through the throttle for a long time, the dust in the air and the engine oil waste gas in the crankcase will accumulate on the throttle wall, which will lead to the excessive opening of the throttle and affect the precise control of the throttle by the engine computer. Too dirty throttle will lead to unstable idle speed of the engine, and it is not easy to stop, so it needs to be cleaned regularly.
