Berk HFC Question

[kbc749]

Hello,

I recently installed Berk HFC's in my otherwise stock system and when getting the demon bolts off, my father used an impact tool, we didn't get the stock cats out that day and the next day I got error code specifying Bank 1 Sensor 1 or Bank 2 Sensor 1 issues. Codes read and cleared and came back, same error. After Berk HFC's installed, codes cleared again and same error came back.


So since Bank 1 sensor 1 is kinda sucky to get to, I took her into the dealership to get it replaced with my oil change. And they claim that the 2 O2 sensors in the Berk HFC's are actually the problem. They claim that Bank 1 Sensor 1 and Bank 2 Sensor 1 are functioning properly and that the real problem is that the two O2 Sensors in Berk HFC are not deep enough into pipe to get a good reading.

So this begs the question, are they just goofballs? I have read that an ECU reset is required to stop CEL after Berk HFC install but not in reference to the sensors not being deep enough.

Before the dealership said this, I was convinced the Bank 1 Sensor 1 was the issue, my father hit that side with a manual impact driver and the bolt didn't break free and the next day I got the error code, BEFORE removing stock cats. But now I'm just kinda lost.

Any help or additional insight would be greatly appreciated.

Thanks,
