What is the reason for the insufficient starting power of Audi a4l?

The insufficient starting power of Audi a4l may be caused by lax valve seal and insufficient cylinder pressure. It may also be caused by excessive carbon deposition at the entrance; It may also be caused by carbon deposition in the spark plug or incorrect clearance; It is also possible that the fuel injector is blocked and the fuel injection quantity is insufficient.

A4L is an electronic throttle. In the electronic throttle model, when the electronic control unit controls the throttle, it will comprehensively analyze the depth of the throttle and the vehicle condition, and finally calculate the current appropriate throttle opening. When the driver suddenly accelerates (treads the pedal to the bottom) at the start, the ECU makes an analysis according to the current vehicle speed and throttle size. Considering the fuel economy and reasonable emission, the opening range of the throttle valve will be appropriately limited, and the fuel injection system will be controlled to limit the maximum fuel injection quantity of the injector. In this way, after the driver feels that the accelerator pedal is stepped on, there is obviously a delay before the car starts to exert its power, which is called accelerator lag. Therefore, the throttle lag is actually caused by the electronic control unit limiting the instantaneous power output of the engine. Of course, it also brings benefits-fuel saving and environmental protection.

If you feel that you are not used to driving a car with electronic throttle, there are also convenient solutions. Buy an electron accelerator and install it yourself.
