There is a lot of oil in the throttle.

There is a lot of oil in the throttle, which may be a common problem in some models. Exhaust gas may also be recirculated and discharged into the throttle.

You need to pump the oil every once in a while (generally 10000 km or every maintenance). If not handled in time, the acceleration will be weak at first, and blue smoke will soon emerge. Oil consumption will be high, and burning oil for a long time will have hidden dangers.

What is the specific reason? You need to go to a 4S shop or a professional auto repair shop, have it checked by professional technicians, determine the cause, and then repair it.

Brief introduction of additional throttle:

Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. It connects the air filter and the engine block, and is called the throat of the automobile engine.

Whether the acceleration of a car is flexible or not has a lot to do with the dirt of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and powerful.
