I was in a rush earlier and did not get to post a detailed explanation.

Actually, no. You do not replace the O2 sensor; not yet anyway.
You need to post the exact CEL code(s) as suggested in the first line in my original post. You are going on the suggestion of the autoparts employees of whom you suspect do not really know what the problem is (or how to solve it). You need to post the exact CEL code(s) as well as give a detailed description of what is wrong (or what you perceive is wrong with the car). Then only can CEGers give a better diagnosis. If you go through all the replies on this thread, (projectsho89, Big Jim and me), none of us mentioned that you should change the sensor. We have only told you where sensor is.
Most of the time, the autoparts employees (or some mechanics for that matter) will suggest changing an O2 sensor when the CEL is on. There could be many reasons for the CEL to be on. The code(s) are a minimum. Sometimes a real time scan is needed but most new CEGers do not have this capability and the autoparts stores do not provide this function. Free reading of codes, yes, but usually not a free real time scan. So, go back to the store, get the codes read and post the exact codes.
