The rev counter is calculated by the ECU. So, having a quivering needle is telling me that you most likely have a bad instrument cluster since you don't mention a check engine light. The engine RPM is based off of the crankshaft speed sensor which also does the plug firing. So, if that sensor was bad, you would be getting a lot of error codes dealing with the engine. In this case, the engine would then go to the cam shaft sensors and figure out the engine rotation and get pretty close so you can get the car to a local service station.
