Emissions Help Needed, Bad.
Emissions Help Needed, Bad.
Setup: 1999 Cali-Spec - Obx V2 headers - Test pipe - Cattman catback
Issues: I recently was throwing codes for all four o2 sensors and a knock sensor, yesterday I had bank 1 sensor 1 relocated about 3 inches to the right along with a new o2 sensor for that port since it was broken from the sway bar/rack hitting into it.
Also, I had the two downstream sensors extended with anti-foulers, (bank 2 sensor 2 and bank1 sensor 2) I used two of them per o2 sensor (as recommended)
CEL didn't come on for about 20 miles, went to leave today and now the CEL is back on, scanned it at Advance Auto and all four o2 sensors are coming up and NO knock sensor.
This will be my last attempt at trying to fix this per everyones help here, any feedback, ideas, someone with the same setup? Would be awesome. Thank you.

What were the specific codes?
There are many o2 associated codes, ie. lean condition, rich condition, signal to low, heater circuit open etc.
Anti foulers don't work. The sensor is still in the exhaust system. The only thing they might do is delay there response.
Post the codes and we'll try to help.

Come to find out when my b1 s1 broke, it popped the fuse, I replaced the fuse and drove 25 miles to no CEL, cold started this morning and got 2 miles only for the CEL to trigger, I went to AA and scanned to receive two codes, one for b2 s2 'no activity' and the knock sensor (assuming the ks is a ghost again)
So, is b1 s2 being delayed for a 'no activity' code as well? Because b1 s2 and b2 s2 are being spaced with the same exact anti-foulers, except I stacked two fully bored anti-foulers, I guess I was supposed to use one fully bored and one with the little hole, but why would only one sensor throw the code and not the other is my confusion...
Any ideas? If b2 s2 has 'no activity' that means it's spaced too much and isn't reading Anything, do I try one fully bored anti-fouler? Do I try one undrilled anti-fouler? Or is b1 s2 just going to appear with a 'no activity' code as well?
