O2 question 3.8
Hello - my 1996 3.8 ran a code saying System too lean bank 2 - also says the catalist mon is Inc. I replaced the o2 after the cat that didn't seem to help- could the one before cat be the real problem? Thanks

The ones on either side of the cat only monitor cat performance. The other two, which are located in the exhaust manifolds, are the ones controlling AFR. Bank 2 = passenger side.
