well, the front o2 is more important, the rear one is basically just there to tell you if the cat is bad. but i would say yes. the car will gain a little from taking it off, and it will sound better.

I got the car back!! The GM Goodwrench tech told me that cat is fine!! The only problem he said is that the 02 sensor acts up at times! Sometimes it will work properly sometimes it wont he said. So I decided to take the car back home and not do anything but probably change the Sensor only!!
If i am shooting a P0430 code than what sensor should I change on the cat??
I might just get 02 sims to go the cheaper way and avoid any future problems !!

no, it does that when the cat is going bad. it will throw a code, then be fine for a few days, maybe even a week, then come back. shake the cat, and see if you hear anything rattle, if so. bad cat. and you say you might as well go the cheaper way and get o2 sims...thats not the cheaper way. the cheapest way is to have the cat removed and have straight pipe welded in. the code will still be there, but the rear o2 itself cannot hurt performance, a bad cat will.

The O2s can get slow causing a descrepency between the front and back sensor and it will trip a P0420 or P0430. Like 99Formula said, bang on the cat when it's cold and see if it rattles, it could still be bad even if it doesn't rattle. I would replace the front a rear O2s and see what happens, if it comes back go give the tech hell. From my past experiances it seems many GM shops are just daycare for grown men, you're lucky if 2 of them can actually diagnose an OBD-II problem right the first time.
BTW: I got my truck back today from the shop and the new cats made a huge differance as far as power goes. The truck used to lay down in the middle of a gear at WOT then start detonating at higher rpms, all of it is gone now. I asume it was clogged, it did rattle alittle at cold idle though so it might have just broke apart inside.

They told me they checked everything and that they were positive the CAT was functioning properly and that it was a bad O2 sensor. They asked me if I wanted to replace it and I said no because it would cost me $400.00 for the sensor part and installation.

I told the representative that i had hooked it up to a OBD2 scanner four times along with getting two other mechanics to tell me that there was a catalytic defficincy. And I made him aware that I should not be liable for that charges, but GM should.
He told me that if it is that it is a BAD Catalytic Converter GM will pay for everything including the estimate. FREE
Here is the catch, He said that if some way or another something else is causing this defficincy or if it is another part that is damaged I am liable to pay $130.00 for the estimate along with the repairs of the Catalytic Converter and everything that is associated with it.
I ended up leaving the car hoping everything will be O.K.
What do you guys think from your own experience and knowledge???

WhiteLTone, If he is lying, who cares. Do your buisness, and dont harrass people on this website. If you are indeed a "friendly neighborhood dealer" then you should be above this. In no place was your particular dealership mentioned, and w/o documentation how do we know you aren't the one who is lying. Go sell some cars, or whatever you do, but dont harrass this guy for seeking additional advice from a group people who do not profit from this situation. And $400 for a sensor. If you were really friendly you would have free estimates, and replace something as trivial as a sensor for free. You are probably on the clock right now. That is why our repair bills are so high. Cause the dealerships hire people like you, who spend their days surfing the internet. Do your job!

Heck the only reason I showed up at the dealership was because the OBDII scanner told me that it was a P0430 code. My buddy whom is a Master Tech, but works for Volvo, told me that the code was a Catalytic Defficincy. I got two other techs to tell me the same thing. I did my research and found that they were right! I came on this board just for a little advice. I spoke to a GM rep and they told me that emissions parts were still covered under warranty.
I guess it did not work that way when I went to the local dealership. I figured that I was just better off going to my local speed shop spending that amount of money on some headers cat and y pipe and I would atleast see some performance results.
That is al no biggie!

well, if it was a p0415 code, and not a p0430...why did you try to sell him a 400 o2 sensor? seeing as p0415 is for the a.i.r. circuit... maybe im missing the connection here, but if i am, someone please correct me. as i do not like to provide misinformation.
