Oxygen Sensor.

Autozone told me it was bad. Now I want to replace it. I haven't done a lot to fixing my own cars, but I am learning bit by bit. This is something I havent done before.

I just need to know where exactly it is (pics would be great), and if there is anything not too obvious about replacing it that would be helpful too.

Thanks much

Which one is bad?There are 2 oxygen sensors,one in the exhuast manifold and one behind the catalytic converter.The person at AutoZone does not know it has 2 oxygen sensors,AutoZone hires idiots that do not know they are talking about.

I had the same problem. I was told by the Dodge dealer in Antioch,CA., Kragen, Napa Auto Parts, and Monument Auto Parts to replace both O2 sensors. It cost me at $320 for parts and labor.
