hey fellas i got a weird one for ya. ok, whenever i crank up my car some times it will say 1/2 tank and say i drive it like a quarter of a mile and it'll be down to 1/4 tank. here's the really weird part, if i park it say that night, w/e i crank it back up, it'll be back on 1/2 tank. could this possibly be some wiring malfunction? or just the guage going bad? or what? it drives me nutz b/c i never really know when i need to fill it back up. i've been just kinda judging it here lately but its starting to get frustrating.

thanks for the help,

Kyle
