sometimes you need to restart the car for that stuff to go away, sometimes after i fill up the gauge stays at empty even though the tank is full...but once i shut the car off and restart it its fine

yup, ive also heard that new edge's has gas gauge issues like every once in a while they wont read right so u just hav to turn the car off and start it up again. hell, ive had to do that at 70mph on the highway lol
