BMW x3 sports mode can't get on at high speed.

There are several reasons why the BMW3 series throttle can't speed up: 1. Dirty throttle position sensor or unbalanced voltage will lead to electronic throttle failure; 2. Use inferior oil; 3. The throttle sensor is faulty. 4. When the performance of spark plug is degraded or inferior spark plug is used, it will lead to acceleration weakness and acceleration jitter. 5. The fault code must be read. The air flow meter and the eccentric shaft position sensor may be damaged, and the engine enters the protection mode. When you step on the accelerator, the cable will drive the accelerator, which is the accelerator. There is a position sensor on the throttle. The control unit knows the throttle opening according to the signal of the throttle position sensor, then calculates the corresponding signal voltage, and finally calculates the fuel injection quantity of the vehicle according to the signal unit pressure. Therefore, if the throttle position sensor is too dirty or the voltage is unbalanced, the electronic throttle will fail and the throttle will not rise when it is stepped on. Inferior oil-water separator can not effectively separate diesel oil from water. After the disintegration of the oil pump, the oil pump port of the oil pump was almost blocked by a large number of impurities. During the normal operation of the vehicle, it is difficult for the oil pump to ensure the normal oil supply of the engine. In fact, the throttle position sensor is a component of the intake system. The engine needs enough empty gasoline for normal operation. If the air intake system leaks or is blocked, when the vehicle refuels the valve, the power supply will drop, the vehicle speed will not increase, and the body will shake.
