That's weird. This is outside my area of direct experience, but maybe... It sounds like the governor is broken, if it has a mechanical one. If it is electronically controlled, there's probably a rpm sensor that may not be working right or the processor is not working right. You might try posting to another forum here that might be more for diesels. I don't expect many here with that kind of experience.
