I have a 1989 Mark VII with 63,000 original miles. The car sits for 9 months in a garage with a dehumidifier running. I now find that the speedometer shows "0" for about the first 10 minutes of driving. Then it comes on and works and the odometer also starts working. During this "warm up" period, the gas gage jumps up and down (a gallon or two) but in the range of what is actually in the tank. When the speedometer starts working, the gas gage works perfectly. Any ideas what is wrong or what needs to be fixed? Any and all suggestions welcome. Thank you. :L :feedback
