YES!!

Near as I can tell the problem is actually in the voltage stabilizer which
feeds power to the coolant temp guage and the gas guage.  It is supposed to
provide a consistant 10volts +/- 0.5volts but mine is reading 11.3 volts.
This makes both guages read high.  The procedure for checking this is in the
Bentley.  You might have a good one around that you could swap in to confirm...
Let me know what you find Ken.

  Anyone else have the problem with their gauge reading high?
