I have had my car nowfor about a month and when I first got it the fuel guage would just stay on full the whole time. well I was driving it tonight and whenI am driving the fuel guage slowly starts working its way down, but then when I am stopped it slowly starts working its way back up to full. at first I thought it was the sending unit but then this started happening. Is it the sending unit or something else?

 

good question... I have a similar problem ..... My Fuel Guage ALWAYS reads 3/4 of the way full AND I think some of the other needles appear "stuck"....
