do you have a fuel supply problem? are you running a supercharger? Mine surges with the supercharger active when Im cruising down the highway only by a few rpm. Also mine will do it when I let off the clutch a little fast in the parking lot and it will bounce like a mad man. when it happens just push in the clutch and if it goes away, let it out smoothly. I hope that helps.
