Another source of a bad ground (I think) can be the bolts securing the
thermostat housing.  I believe these bolts are the path to ground that
the sending unit relies on... if they are somewhat corroded they can
increase resistance and give a false low temp.

Never had an intermittent failure from this but when it's a failing
ground many strange things can happen.
