So I've already checked the can stall box and using friction disc with manual transmission. Also, the auto shift is off. Then I'm entering the first gear without engaging clutch pedal. In the real vehicle, the engine should be stall and should be off, but mine was not, the car is always running the engine and keep running, how can I stall the engine and turn off the engine when I do not press the clutch pedal for the first gear?
