    What codes? If you don't have LT's yet and your throwing O2 codes, what are the codes? If it is just bad O2's on the rear side, they just rat out to the computer. they don't actually make the computer change anything, they just check that the system is working normal and that the cats are doing thier job. If the front are throwing codes that can be a problem and you need to find out what is causing it
