Changed the O2 sensors, plugs and wires. Tripped the Ign 3 times after battery was disconnected for 1 hour. 30 mins later check engine light came on. OBS said passenger oxy was gone. Any info?

i have heard on more than one occasion that people have gotten bad oxy sensors out of the box maybe take it back and try another one ?
