What is the feeling of rushing when Audi starts?

When Audi started, it felt like a rush, a rush and a setback. I should consider the throttle first. If the throttle is too wide, there will be a feeling of rushing and retrogression when starting automatically. In addition, the problems of oil system, electrical system and ignition system will also make Audi auto start feel frustrated. For example, the isolation pipe of the air intake system leaks, the ignition coil is damaged, and the life of the spark plug reaches the limit. If there is something wrong with the accelerator of the car, it will cause the Audi car to start with a rush feeling. The solution is to clean the throttle. After clearing the throttle, the driving computer needs to learn the driver's driving habits again. The main function of the throttle is to control the intake of the engine. The air intake of the engine affects the fuel injection quantity, and the fuel injection quantity will increase accordingly with the increase of air intake. When we step on the accelerator in our daily driving, we do not directly control the amount of gasoline injected, but control the opening of the accelerator. So the throttle is also the throat of the car engine. If there is serious carbon deposition in the throttle, the car will be blocked from starting.
