Answers to the questions above,

-Berk Hfc's are used. Hadn't considered this issue. Will look into it, although bought from this forum and owner was stand up guy and didn't have any issues.

-Yes the O2 sensors in the cats were removed when my father used manual impact tool, but the O2 sensor in the header is the one that threw the code after impact tool was used, which I didn't even think of until after he was banging away.

-I have cleared codes 3 times and the same code has come back every time
The first time was before Berk units installed but after impact tool
The second time was after Berk Install
The third was when doing ASWC-1 install when I disconnected the battery.
All 3 times the same code has returned.

Now Nissan is claiming that the Berk HFC's are at fault for the issue. That the o2's in the Berk Units are getting no reading, causing the header O2 sensor to throw a code.

But since I was throwing codes before the install this doesn't make sense to me. But they claim to have checked the whole system and all 4 of the Sensors are in proper working order.

Any thoughts?
