What is the tempering of 4000 throttle valve for grand Cherokee dust collection?

Hello, there is a little carbon deposit in the throttle body, which will cause unstable idle speed, difficult starting or flameout during driving. If the vehicle is driving in urban areas for a long time, it is recommended that you clean the throttle body every 10000 km/time. If it's convenient, it's best to run at a high speed every 1 month/time. It is easy to deposit carbon when the vehicle is in low gear and low speed for a long time.
