2004 gto trouble code P0154 Engine light came on out of the blue. My gto started running rough at idle. Trouble codes were; running lean, P0154 o2 sensor no activity bank 2 sensor 1, and missfiring. could my o2 sensor just go bad? no exhuast work. was running good for months. I checked my air intake for leaks and found none. Can any one help? Thank you in advance.

Found the problem. I was the O2 sensor but it wasn't a bad sensor the wire was torn in two spots. Must of ran something over becuase the clip was uncliped and plastic anchor was pulled away . It was also on the passenger side which made it alot easier to change becuase of easy access.
