you need to have your tuner delete your rear o2 sensor codes. they just tell if your converters are working correctly

theres no way they'd die within a day.... they're either not connected up properly or the harness has been melted along side the headers..

swap the ones that were in the back up front assuming they have the same connector. Mine were the same and when one died I just threw one of the rear ones up front.

my 2000 had different connectors, but you might get lucky and do what scott did
