i have a 04 liberty 5 speed. i keep getting a check engine light. there are three codes. one is bank 1 sensor 1 lean, bank 2 sensor lean, bank 1 sensor 2 lean.
i have changed both o2 in the rear. my jeep has no power and is getting about 10 miles per gal. it also kicks or bogs down when i need the power. when i get on the turn pike it takes me 1/4 mile to go from 45 - 65 mph. any ideas would be lovely right now.

Well did you change the front O2 sensor as well? Don't use bosch O2 sensors,only use Denso or NTK(NGK) O2 sensors in a Chrysler.
Could also have other issues like bad cats or a intake leak or low fuel pressure.

Doubtful. I would verify you have proper fuel pressure before going further. Once that has been ruled out, there are a couple of areas you need to look at and verify.
