Hey mate, sounds like the engine RPM sensor is out of wack that needs replacing or fixing.

Alternatively, the problem you describe has NUMEROUS causes. Most common of these is a COIL is going bad. I upgraded mine to Spitfires and never had an issue again. The RPM gauge gets its signal from the ignition coil/crank sensor circuit (could be either one OR could be the wiring between the engine control module (ECM) and the engine components. Does the Check Engine light come ON when this happens? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there.

Besides the gauage not working, are you noticing the car running funny, e.g. pining, more laggy or not performing?

I suggest you bring it to a mechanic for a better diagnosis.
