"Its back!"
Replaced pre-cat O2 sensor last week after pulling up bank 1 sensor 1 low voltage code. Replaced with a Walker sensor from oxygensensors.com. A week later the code is back. Tested the sensor with a code reader and the voltage varied from 0.85 to 0.05 volts. Could it be a bad replacement sensor or should I just have gone with a Bosch sensor in the first place.
Any suggestions. All input is appreciated.

Agreed... you should always go bosch, if its good enough for mercedes and AMG then it's good enough for me. I am of the mindset that it's worth doing right the first time even if it's a little more expensive, you will usually avoid redoing the job later.
