Has anyone had issues with codes being thrown when they have BBK LT and o/r H or X pipe? I just bought my car, it has had BBK LT and O/R H pipe for some time. But since I have had it, it has thrown a p2195 and p0430. When it threw the p2195, I found that replacing the o2 sensor on that bank w/ an aftermarket one (ford motorcraft was causing STFT to be off) worked. NGK I have on it. But since I have MIL eliminators on I don't know why it is throwing the p0430 code. I have read that LT headers don't heat up enough for the o2 sensors to read correctly.... Any thoughts???

 

Two things:

1. The tune needs to be modified with the front O2 sensors staying in open loop for a longer time after a cold start.

2. Either the rear O2 sensors need to be disabled in the tune, or MIL eliminators installed at the correct angle in the midpipe to fool the ECU.
