Well sort of... I installed test pipes probably about 4-5 months ago and got an SES light the day it was installed. I didn't think much of it, figured I'd give the nonfoulers a shot even though I have an 03. I recently tried the nonfoulers and still got it. The code I pulled previously was a P0057 which I believe is the O2 sensor. I went ahead and installed nonfoulers, cleaned the MAF and TB a little and of course about 5-6 miles down the road it came back on.
I've noticed that just above 2.25k RPM's it seems bogged or something. In first it sort of dips and picks back up once you pass it. Once you get to higher gears its not as noticeable but if you cruise right about 2.25k it seems weak. Also, when my car is idling with the AC on, the RPMs fluctuate up and down, not much (about 100rpms) but definitely noticeable. That didn't start to the test pipe install.
I'm sure that most of you would recommend me change my O2 sensor for my SES light but anyone have any idea if a bad O2 sensor would cause those problems for sure?
Thanks for any advice.

I cleaned it with CRC MAF Sensor cleaner. I believe a few other members used it here and haven't had a problem with it.

First you need to find what the exact code is. I can tell you that is not a code for the rear O2 sensor. For I've had this problem before. That code would be P0430 and P0420. I've been told that O2 sensors don't go bad, but that might be some BS. I used an electrical O2 sensor simulator to fix mine due to at the time I didn't know about the fouler kits. Could of saved me 95.00. That might be a suggestion pending on your problem.

I think I may order an O2 sensor soon and see. I think my friend may have hit near the area where the O2 sensor was to get it out and possibly damaged it. I dunno, figured it was worth a shot.

Recently, my rear (by the cats), passenger side O2 sensor wires (all 4) were cut somehow. That's (I think) when I got the P0037 and P0057 engine codes. I just rewired them for the time being, did a reset, and got rid of the P0037 code. However, I'm still left with the P0057. I don't see how rewiring them could've made the bank 1 code (P0037) go away, yet leave the bank 2 (P0057) unaffected.
Did you ever find out how to fix the P0057 code? I have that on right now and I can't seem to find the solution to it. I know it's for the "O2 sensor heater circuit," it's the bank 2 (by the cats?) sensor 2 (passenger side?), and that it's low voltage (which means lean?). I found that out through searching multiple sites. Confirmation to all the above info and a fix would greatly be appreciated.

I ended up replacing both O2 sensors sense I wasn't sure which O2 sensor was bad. After I replaced them almost a year ago, I haven't gotten a SES light since.
I actually thought the low voltage meant it wasn't getting any reading from it because it was damaged. Wasn't cheap but it definitely fixed it.

i had to replace one on my 06 stupid exhaust shop didnt use locktite on the o2 going into the nonfouler and it vibrated out. Hit a bump while driving, had a exhaust leak from hell i thought a bolt came out got home all i could see was wires dangling. Cost me i think 148 through the nissan dealer. took forever to get here though nobody stocks 06's lol cause nobodys stupid enough to break them except for me of course.
