Where is the oxygen sensor located and is it easy for me to replace if I purchase it separately from the auto store?

I know a little about the mechanical part of cars, but not that much...?

Thanks, Dan

Hi:
the sensor will be up stream from the cat conv. THey are easy to replace. Un plug the wiring, unbolt and remove the O2 sensor and replace it with the new one.
