“Under normal driving condition engine started revving up to about 3500 RPM as if I pressed the accelerator pedal. Freaky experience but luckily the road wasn't too busy. I slowed down to the side of the road (was driving in portland oregon inner city area) by pressing the brakes and flipping the car into neutral but the engine kept revving up around 3000-4000rpm. When I turned the engine off and started it again, it wasn't so bad but the engine was still revving up and down by itself between about 750 and 2000rpm. …”
