The car ceases to accelerate (Forza Horizon 4)

On the PC are faced with the problem that the machine loses speed, tobish literally ceases to accelerate. It seems this is due to the switching gear (switches and then you need again to press forward, otherwise the speed will not grow) when I started doing it manually, this was not. I understand that there is the clutch, everything works, but I have all automatically worth. What on the joystick that is on the keyboard - the same problem. This makes it impossible to play normally, everyone overtake. Somebody faced with such and how it to solve?
