well 4x4 makes a difference, I'd still expect like 13-15 city and better on hwy though. Tune up would be good if it hasn't had one. Also, differential fluids will make a slight difference. The o2 could be going bad, the one after the cat from what I understand is just for emissions and has no effect on air/fuel ratio. An o2 could be going bad and still not throw a code.

I have an 07 4.7 i get around 13 city and 19 hwy i have a k&n CAI and a flowmaster dual exhaust. i would do a tune up. Im trying now to save money and get a programmer that should help me out with a little. the other thing that i came to find out is its a big truck with a smaller motor so its going to take more to get the truck moving.
