So my fuel gauge is being buggy.. its fine on a full tank till it gets about 1/2 then around 130miles *trip* it will go.back to full. Just today I noticed while i was idleing in park in my garage, it slowly started to read correctly. But after driving about 5 miles it went back to full. At first I thought I thought the Sending unit was busted. But that can't be since it will read over the whole spectrum... help? Lol
