Jumpy Temperature Gauge

I was wondering if anyone else has had a similar problem and hopefully a solution. My SD runs at about 95-96C (ambient air temp being ~90F) on the highway doing 65-70 mph but all of a sudden the temp gauge will jump up 8-10 degrees(instantaniously) run there for a while and then jump back down to what I consider normal at 95C or so. It acts like there is a short of some type sometimes and it will jump up and down real quick. Also the fuel gauge has the same problem but they dont seem to be syncronous with each other.

I am thinking of replacing the temp sending unit and the thermostat. I am sure that the problem is not the thermostat because of the instantaneous reading change. I gues pulling the instrument cluster and looking for obvious shorts is also a consideration.

Has anyone had a similar problem and fix??

Stephen
