Hi: I?m new here. I have had an ?84 Corvette for 7 years, and put
7000 miles on it. As you can see - I don?t drive it too much. I don?t know what I have been saving it for. Anyway, I put a Battery Tender on it as the battery was always going dead from sitting too long. I mention that because I thought maybe it messed something up. All of a sudden when I estimated that I was going about 35 miles per hour, it was registering 60! At about 50 mph it registers 90! My brother told me to disconnect the battery cables for a couple of days. I did that, but it didn?t correct the problem. Also, the fuel mileage is horrible. I used to get about 19 around town, and I recently went 9 miles, and used about 1/2 tank. I would be eternally grateful if someone could help me. I spent $200 on a new dashboard a couple of years ago, as none of the lights were working. Everytime I used the cigarette lighter it would blow out everything. How come as soon as a dealer sees a Corvette coming they increase their prices??????????? :twisted:Thanks in advance for any help, Joni
