Replacing it is entirely up to you and how comfortable you are with doing the work your self.

Here is some more info on that part.. page down once to see how it fits in the motor.. GL what ever you decide to do.

Easy job...should be a bunch of posts on oxygen sensors...If i remember correctly Bank 1 Sensor 2 is the oxygen sensor after the cat. Just look underneath for the thing threaded into your exhaust pipe between the catalytic converter and the muffler. Spray a whack of PB blater on it, warm up the engine for about five minutes, cut the wires off so you can fit a deep-well socket or wrench on there (or buy an O2 socket) and have at 'er!
