I was told that my oxygen sensor at station or stage one, sensor 2 was bad. Where is that located and is it something I can change myself?

it is located on the side of the engien with the #1 cylinder.

it is on the exhaust piping AFTER the convertor.

buy the special tool used to remove it from a autopart store. and make sure the vehicle is warm before attempting to remove it.

when installing the new one, use antiseize compound on the threads.
