I have an 88 Olds Frienza I drive to work in. Lately the gas gage goes way high, about 1 inch above full almost every time I turn on the ignition, but is intermittent. Banging hard on the top of the dash a few times usually brings the reading back to normal. Sounds to me like a maybe a ground is loose, or maybe there is a mechanical vibrator-like voltage regulator that is sticking closed. Any ideas on what to check?
