Do you mean your RPMs don’t drop when you let go off the accelerator pedal?
Well it's easy to tell if it's the brakes as soon as it starts doing it pull over jack up the car and spin the wheel see if any of them are sticking. If they aren't then you'll need a guy like me to road test it with a scan tool hooked up and when it acts up that data is recorded and could be analyzed to see which system is acting up
