In the morning, the engine failure light came on, and driving was very frustrating. No throttle failure was detected during refueling.

Damage to the solenoid valve is an important reason for frustration, just like being kicked in the back of the ass. Setbacks can be divided into occasional periods and fixed periods. The difference is simple. Accidental means irregular, fixed means reaching a certain speed or changing a certain gear (second gear into third gear) and a fixed speed appears. Bian Xiao thinks that the reason why your car is frustrated is that there is sludge in the gearbox oil circulating in the gearbox that blocks the oil passage in the valve body, which will lead to a series of gearbox problems such as high temperature, impact and slippage of the gearbox for a long time.
