So I installed Longtube headers and got error code P0420 and I installed Spark plug defoulers on the 02 senor to get rid of them but now I get P0157 and 137. Anyone know how to fix this?

Also tuning out the 02 sensors is impossible with every tuner that exist now because they’re all frightened by the EPA.

Autorocect suks? Or maybe the lack thereof, given these words don't seem to exist, unlike statistic and infamous I know the feeling, these frikken phone screen keyboards are for mice, I swear.

Take those stupid "defoulers" out and properly tune the car for the headers. Problem solved.

Maybe a few years ago that would work but Like I said tuners aren’t allowed to go anywhere near the 02 sensors anymore because apparently the EPA is really cracking down and all my stuff is updated. As long as there is that much air going through to the sensor the Check engine light will stay on.
