Goyle's engine broke down while driving.

The colloid on the inner wall of the throttle is so thick that at the initial stage of throttle opening, although the throttle has started to open, the colloid on both sides of the intake gap is blocked, and the intake air volume cannot be increased accordingly, but the throttle position sensor has rotated, the idle contact has been disconnected, and the idle valve is closed. The electric signal of the throttle sensor has been transmitted to the computer, and the fuel injection quantity has started to increase, so the mixture is too rich and the combustion is not good at the initial stage of throttle opening, and the engine power cannot be properly improved. When the throttle valve continues to open, the colloid blocking effect decreases, the air intake suddenly increases, and the engine power suddenly increases, thus forming the phenomenon that the vehicle suddenly rushes forward.
