New O2 Sensor?

I bought a used 1994 Toyota Camry V6 XLE a few months back, and for almost 2 months the "check engine light" has been on. I had the dealer run a scan and he said that the problem was with the O2 sensor. He also said that he would clear it, since somtimes it comes on because they start the cars up alot without driving them around. (I also bought a used car from there previously, and the engine light came on with the same problem, but that went away after a couple months, so i thought it was the same with this.)

Anyways, I do alot of city driving and my average MPG is 20-22, so its not too bad, but a couple days ago I started to smell a sulfur smell coming from the exhaust tip.

So my question is, does it sound like I need a new O2 Sensor? And if so, would it be pretty easy to replace myself?

Also, if I do need one, how do I know whether its the front or back sensor? Or do I just replace both?

Did they replace the sensor the first time or did they just clear codes?

As far as I know they only cleared the codes. He looked it up and said it would be $200 for just the sensor(s) if I want them replaced.

Need to know the code. The code will tell you which one.

This is something!!!

The light tells you that there is something wrong with the car. It does not matter how many times you will reset codes. They will come back. And the only reason for this is that it has never been fixed. This is the way your car communicates with you. This is the way your car screasm: "HELP!!!"

Never go to this dealer again!

Go to Autozone. Read the code. Post it here. I am sure somebody will be able to translate it for you.

Im not near an autozone now, but I will be tomorrow.

In the mean time, would these be compatible with my car?

I often shop Kragen but my favorite online store is www.rockauto.com (http://www.rockauto.com)
If you are not in a big hurry wait a little. I am expecting a 5% discount from them in a week or two. I will post it here.
