If the gauge goes up within the first minute of running it from overnight, etc, you have a sender switch, temp gauge or possibly wiring problem in dash or main harness. There was a bulletin GM came out with in 91 or 92 that by-passed the temp switch in rear cyl head by splicing the wiring directly into the coolant sensor switch near throttle body. That was to fix a high temp reading because the cyl head temp switch was located too close to # 5 cyl exhaust port, I believe.
