The throttle of the Big Dipper is very heavy.

The reason for Beidou's heavy throttle may be that the spring under the accelerator pedal is too hard and elastic. You can use pliers to break the end of the spring hooked on the pedal in the opposite direction to reduce its elasticity. It is also possible that the throttle is dirty, resulting in inaccurate oxygen sensor. You can look at the engine data flow or check the pressure of the gasoline pump. At present, the gasoline pumps of all cars are placed in the fuel tank, and too little oil will affect the refueling situation.
