Wildly fluctuating oil temps

[mike mcclurg]

Does banging on the dash near the gauge matter? I had
this happen with the oil pressure gauge on my '89 100q
and I finally decided it was a loose wire, loose
connection or just some conductive dirt in the gauge
itself. Although I have yet to tear down the dash and
prove it.
