I had this problem too. But mine problem came up a few weeks after installing longtube headers, which I suspected (at the time) was the problem.
A great thing to try in debugging this is to swap the front driver & passenger side O2 sensors with each other. Then clear your codes. The code will likely come back and hopefully the code is now for the other side - which would mean you simply have a bad O2 sensor. That was the case with me.
