Bank One Sensor One is the sensor left side drivers side. Check the sensor for fouling, if the senor is bad it usally wont run for crap. I kept getting that code and replaced the sensor with no improvement. Every one was telling me to look for a air leak. Couldnt find one finally I did the the trouble shooter on my Scan Tool it said to check for the rear sensor sensor 3 behind cat. Turned out the rear sensor was bad and throwing the bank one sensor one code. Replaced the #3 Sensor and solved my problem. Sounds like you might have damaged the wires or the sensor .
