I don't know any of that, if I did I'd see if mine were bad cuz I think mines messed up. Do you reset your trip odometer? If so and you know roughly how many miles to the tank you get just go by that and don't worry about it, thats what I'd do. Or just take the possitive (?)(I think that's the cable to reset the computer) cable off the battery and reset your computer and take it for a drive around the block and see what it does.
I'm just throwing out ideas here, so of course they COULD be wrong.
