I have a 2020 Mini Cooper F56. Last year, I started the car and noticed the RPM was steady between 2000-3000. The same thing happened today. When I stopped at a red light and turned off the start-stop system, the RPM was at 1000. But as soon as I pressed the accelerator, it went back to 2000 RPM and wouldn't go down. Normally, the RPM is just above 1000. What could be the issue?
