Peter,
I don't know why it would do that and I promised my wife I wouldn't think
about it. But I probably will think about it. Who knows?
Have fun,

If you look, you'll see your other gauges are jumping too--fuel quantity and
oil pressure. Mine do the same thing, and it's quite annoying.
Electricity is all PFM to me, but I believe the issue has to do with
inadequate grounding of the gauge illumination circuit. In my car, the
gauges jump
when the first position (parking lights) are selected also.
In the short term, I am just keeping it in mind and adding a mental
correction factor whenever the lights are on. In the longer term, I'm
hoping I can
sic an Electrical Guru on it.
I have a sneaking feeling they're going to tell me to do something I really
don't want to have to do--reach under the car and clean/improve the
grounding
at the stud that's buried somewhere under the dash. Groan.
Mike
