throttle input problem

Can you describe your issue in more detail? Are you using a controller or a wheel (what type)? Is this a new issue or has it been going on for a while?

Throttle cuts out and it will start changing gears also it wont pick up the throttle input. It's been going on for some time. Steering wheel Logitech G923

You could try cleaning out the potentiometer on the pedal, or you could try recalibrating it in the logitech software. If you have not updated the wheels firmware recently, I would do that as well.
