The throttle is dirty and it is easy to stall.

Hello: Regarding your question, when there is too much carbon deposit in the throttle body, whether driving at low speed or high speed, the flameout will occur after releasing the accelerator pedal. The flameout during driving will affect the driving safety, so it is recommended to clean up the carbon deposits regularly. If you drive in urban areas for a long time, you can clean the throttle body every 10000 or 15000 kilometers according to the actual situation. If the vehicle runs on the expressway for a long time and the air quality is good, then the cleaning cycle can be appropriately extended.
