Getting Fed Up!!! Please Help!!!!
So my check engine light came on the other day, and I did what most of you on here would do. I pulled the codes. Came up with 4 codes, which all corresponded to the 4 O2 sensors. So I went down to Autozone, bought the correct replacements, and finally had time last night to install them. Tested everything out and things were perfect. Drove to work this morning, and every was great. Drove home from work however, and on comes the check engine light. I pull over and what do you know, the same 4 codes for the O2 sensors. I reset them real fast, and drove home. Now the car is even idling rough....really rough, and every time I start the car the check engine light comes on with the same 4 codes. Where did I go wrong? Please help me, this really sucks. Thanks in advance.

But they're the same sensors...They're made from Bosch, which from my understanding is pretty reputable. The correct model numbers for the car. Same ones you can buy at napa. I just have a hookup at Autozone.

How do you know he didn't get a good brand? Borg-Warner, Bosch is good brands and are sold at AutoZone.

You may have other problems, but when you replaced the rear sensors, did you plug them into the correct connector? If I recall correctly, they cross. right to left, left to right. Verify this is correct, before you do it. I don't want to give bad advice.

I have done nothing to the car in roughly 2 months, and that was only seafoaming the fuel tank to fix the gummy fuel senosr, which is what I thought might have caused the old sensors to finally go.
And as far as crossing the wires, I did one at a time, so there was no way to cross them because I finished each one before moving on....
I am so perplexed by this.

Faulty O2 sensors?
Still got the old ones? I'm sure they all are not bad.
So, put them back in. Now, one at a time, replace an old one with each one of the new ones checking the light after each replacement. If all four new ones fail assume the old original is OK, put it back in and move on to the next original sensor again trying each new one in its place, etc.
Here's my story. I had this problem on a Jeep Grand Cherokee. Took it in for a tuneup: plugs, wires 02 sensors, etc. Got the car out. Soon after "Check Engine" lit up. Never did that before.
Oh, I forget to mention, the new o2 sensors were from Jeep.
Long story short. The federal warranty on emission parts had not expired (70,000 miles or seven years (i think)). I ended up taking it to Jeep 10 times. Each time a new part in the emission system was replaced but each time the car failed smog and turned on the CE light. Jeep changed (under warranty) EVERY EMISSION PART ON THE CAR (ie. new cats, pumps, new PCM, new hoses, new EVERYTHING!) Over $5000 in emission parts were replaced over two months.
After 10 failures and calls by the dealership to Chrysler engineers who were no help I said, "Why don't you change out those "new" o2 sensors that were put in during the original tuneup with another set. Jeep hesitantly said OK because there were no more parts to replace. So they did it. The car passed smog! Never had CE light again. Car now has 90000 miles on it.
So, maybe one or more of those brand new sensors is bad.
I hope its something else but, you've got enough old and new ones to do some experimenting. Just keep good notes as you experiment.
Good luck!
