If the water temp is changing quickly and/or jumping 2 or more dots at a time, I suspect the sensor or wiring. If the swings are slow and steady, then Jordo! may be on the right track with the thermostat. Or it could be a faulty readout.

Try monitoring water temp directly from the ECM with an ODB/CAN monitor.
