I was driving my car, came around a corner hit the gas and all at once blaahhhh... it crapped out on me all of a sudden. I got it home checked the codes, It threw 21, 27, 28, & 29. 21 & 28 are main o2 sensor codes, and 27 & 29 are sub o2 codes. I replaced the front two O2 eliminated codes 21 & 28.

Now ares far as the 27 & 29, I have replacements for the Sub o2 but could not figure out how to change them. They are easy enough to get to, but the wires run up into the body of the car.

Has anyone every had to change these before?
Am I going to have to pull out my carpet and get to the plugs from the inside? or should I just cut the wires and slice in the new o2's?
Thought I'd get some opinions before i did anything

There should be a connector under the carpet inside the car. Your going to have to pull the harness threw the floor board. Never cut 02 wires cause I have seen people run into electrical problems doing that.

Update:

so when I said my car crapped out on me, it was running super rough, no power, would barely stay running. I pulled the wires off a couple of the spark plugs, and came to the conclusion that i had a bad coil back. I replaced it, It fixed that problem, but I'm still getting o2 codes, as well as code 55.

When I start my car up after it's been sitting all night, I will run fine (and fast btw) for a couple miles. In this couple miles the check engine light and track off light will come on for a little while, then shut off. it may do this as many as three times while I'm driving. but after a couple of miles the check engine light will come on and stay on, and the car will go into safe mode. during this time I get codes
21, 27, 28, 29, & 55

The crazy thing is i dont always get 21 & 28 some times it's just 27, 29 & 55
I'm assuming that 55 (knock sensor signal) is what's putting my car into safe mode.

Just to let you'll know, I have recently done a lot of maintenance work:
New timing belt
New water pump
New plugs and wires,
New knock sensors (yes i was getting code 52 & 53)
EGR delete (i was also getting 71)

I have also replaced all 4 o2 sensors. I bought the mains off of Aliga, and the subs are universal Bosch. Yet I'm still getting all 4 o2 sensor codes, the same as I was before I replaced them.
That lead me to believe that maybe my cats were clogged.... so I hollowed them out lol.
As far as codes and behavior goes that made no difference. It did make it sound pretty sweet and I pulls harder, (before going into safe mode that is)

I am now starting to wonder if I have some kind of intake leak somewhere, if so would this cause my car to detect a knock and set the o2 codes off?
It baffles me how well the car runs first thing in the morning, before going into safe mode.

let me know what you think.

oh yeah and before any one asks, yes i have disconnected the battery bfor at least 30 mins, and i have ran fuel injector cleaner through it.
