Cleaned battery, but didn't change it out for a new one? I doubt that's it at this point, unless it's somehow freaking out the computer (that's tech talk). I've had batteries going bad that made a watch run faster instead of slowing/stopping.

Bad cats would give bad gas mileage, and I'm sure the cat related codes would be thrown.
