You probably put the o2 sensors back in the wrong spot (swapped left to right.) Try swapping the 2 front ones if it's upstream, or the 2 rears if it's downstream, then reset the ECM. If this doesn't solve the problem, the o2 sensors themselves have probably seen better days (I believe "lazy" is the term.)

the back o2 are in the right spot so you are saying switch the front ones around

Well, what exactly is your code? You said bank 1 and 2, that tells me passenger side and drivers side. There are 2 on each side, upstream (before the catalytic converters,) and downstream (after the converters.)

If your rears are ok and you're sure, switch the front ones around. Before you do that, check the whole thing for leaks, and if you find one and fix it, disco' the battery with the door open to reset the ECM and make sure it wasn't just a bad leak.
