What should I do if the idle motor fails? What is the general reason?

What if the vehicle can't accelerate? It is caused by carbon deposition in throttle, idle motor, intake and combustion chamber and spark plug. It is also possible that the acceleration is weak due to sensor failure. It is suggested to solve the problem by cleaning the throttle and engine carbon deposit. The easiest way is to drive the car to a spacious place, open all the doors, turn the fan to the highest level for a few minutes, and then clean it with air conditioning cleaner. However, the cleaning agent cannot clean the inside of the air duct. It is recommended to go to a professional repair shop to clean the air duct, usually once a year. What should I do if the car often turns off at idle speed? Automatic transmission models will not turn off easily, while manual transmission models may turn off frequently due to the driving level. However, it is not excluded that the automatic transmission will not turn off. The main reason is that the use of inferior fuel leads to carbon deposition and the engine will stall.
