I would adjust the TV cable, tune it up (start with plugs, pull one out and check them), is the check engine light on?
I noticed the 703 injectors alot (highly recommended)
I feel like the o2 sensor is the only thing if the Jeep runs ok, that can kill the mpgs that bad!
The last thing I can suggest is to reset the ecm, because it's adjusted to the previous owner. Reset it after each change you do! And report it in this thread, maybe run a tank each change. You should be getting around 260 mile + out of a tank. Good luck and hope to see some increase.

noticing a 1mpg drop with the higher ethanol gas. Watch for the sticker on the pumps, if they use more than the state reg. amount they have to put a sticker on the pump. Just noticed that my Costco put a sticker up...

My 2001 automatic is mostly stock on 30" Cooper AT3's and gets around 21mpg on the highway and around 17mpg in the city.
