Neuspeed N2 header
Random Tech cat (w/ non-fouler trick)
Tanabe exhaust
The header and cat were installed at the same time and I ended up with a CEL for the secondary O2 sensor (not sure on the exact code as I used the paper clip trick). Two spark plug non-foulers were used to clear this CEL.
After a reset, another CEL came up, this time for the primary O2 sensor. I now have a scan tool so I know that the exact code is P1165 (Primary heated O2 sensor circuit range malfunction). I swapped out the current O2 sensor with a Denso, no luck. I swapped out the Denso for a Honda one this past weekend, also no luck. I've been clearing the codes with the scan tool, not by pulling the battery but I don't think that it matters.
It has to be the header that is causing the problems but I'd rather not swap it out. The only other possible solution that I can come up with is to try the non-fouler trick on the primary O2 sensor. I don't think anyone has done this before, though.
Any other suggestions? Thanks in advance.
