bad voltage regulator (on back of inst cluster) might be the problem. 
It makes 10 volts for the fuel and coolant temp guages so they are
consistent regardless of the cars operating voltage.  It's a three
legged transistor thing, try measuring it's output, which is first sent
to the fuel and coolant sensors, then thru the gauges to ground.
