So here's my issue...
I recently replaced both O2 sensors on bank 2.
Within a week, I had the P0430 code pop (Catalyst Efficiency Low). I cleared the code and drove for a week before I went on a 500 mile trip and the CEL popped again.
The vehicle idles fine and revs to over 5000 RPM fine when in park. Once in drive and under power, it chugs and sputters.
Is it possible that I have a defective sensor out of the box? It seems to me that a clogged cat would cause it to run poorly in park as well as under load.
Any thoughts would be appreciated. There are no other symptoms but the poor driveability under power.
