Okay so I've done some searching and I wanted to make sure that what I came up with was right.

My car flunked emissions the CO2 value was 24 and the threshold is 20. Recently I had an engine light for Front Left O2 Sensor. I've also had my rear sensor go bad a while back.

* From what I gather (if i was cheap) I would only want to replace the front left sensor. This should help the fuel mixture I believe?

* The rear sensor doesn't have any bearing on emissions?

So i pulled up the Rock Auto catalog:
http://www.rockauto.com/catalog/x,ca...,parttype,5132

and there are TONS of sensors. Could somebody offer advice as to which sensor I should buy? I believe some you have to "crimp" wires and some you don't? I may just take it to the shop to have it installed but I was hoping somebody could offer some advice.

Thanks so much for all the help information on this website.

I just changed my O2 sensor on the front right (back header) and it was easy. I just went to advanced auto and picked it up prewired. All i had to do was screw it in and plug the other end in... It was very simple. did it in 30 min with a HOT motor.

all o2 sensor need to be in working order for you to pass emissions. The rear o2 sensor checks the condition of the main cat.

Well,

I passed emissions. My CO or CO2 levels went from 24 to .7 when only replacing the front 2 O2sensors. The rear one is still out of wack.
