Hi guys, today I drove to the canyon with some friends. On the way back, Downhill the engine started revving by it self, when is on neutral. It revs from 1.5k RPM to 2k RPM, and sometimes it does it from 2k RPM to 3k RPM by it self. I really don't know what is going on with the motor, have this happen to anyone's motor before? I have a k20a2 by the way, around 33000 miles on it.
