What's wrong with stepping on the accelerator when the red flag h5 is mixed?

The throttle valve is damaged. Hongqi h5 hybrid electric vehicle is a medium-sized car under Hongqi. When I stopped, I stepped on the accelerator and didn't respond. The throttle is broken and needs to be replaced. Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be successfully formed after combustion. It connects the air filter at the top and the engine block at the bottom, and is called the throat of the automobile engine.
