Front O2 Sensor voltage too high!!!

After troubleshooting numerous idle problems with the assistance of both forums (see below) we were able to determine that the source my problems was my front O2 sensor, which was reading 1.28v constantly right from start-up. I swapped in a new sensor, and guess what, no change.

Question1: What are some possible causes for the constantly high voltage from the front O2 sensor?

Question2: Worst case, can I just wire the O2 sensor directly to the ECU? If so, how difficult would it be?
