Default o2 sensor switching from 30 to 900 millivolts

I have a new o2 sensor and after a minute or so it starts to switch from 30 to 900 millivolts and the smell makes me think its running really rich?

It misses really bad if I try to drive.

It runs fine if I unplug the o2 sensor?

Problem solved by replacing a Bosch o2 sensor with a Standard o2 sensor. The 1st Bosch I had returned because I thought it was defective. The 2nd Bosch made my car run the same way (really bad) Im going to return the 2nd one Monday and tell them I want my money back.
