The best way to figure this out would be to go to a certified automotive mechanic.  It could be the sending unit (i.e. Sensor) it could be the wiring, it could be the motor in the cluster (dash).  Any number of things could be malfunctioning

There is a sensor in the side of the block that may be the problem.It is between no 1 and no 2 plug.
