  Most likely bad solder joints on the circuit board behind the instrument
cluster. Hit on the dash is the telltale symtom, which temporarily fixes it.
On mine, the odo would not register correctly either.  Many listers adept at
soldering have fixed it themselves. Mine was fixed by a lister for the
equivalent of a few cold ones. Not a big deal.HTH
