Replacing a sensor behind a cat won't do crap after you hollowed them out. It's what is causing your problem. It's trying to read clean air and changing you fuel curve according to the reading it's getting. The reading it's getting is wrong because of the lack of proper cats.

Like Matt said, the sensor is not bad, it cannot compinsate for the change in exhaust gas's coming out of the cats. I believe I said that in my first post.

Cat's don't cause problems. NO CATS cause problems. You'll continue to have issues until you fix that.

Spin Tech or Magnaflow offer some of the best I've had on my car. Spins will free up the most tq.
