[QUOTE="JUIC3D, post: 14049327, member: 123069"] Another fix is to wrap the sensors with header wrap to keep heat in the pipes. I put long tubes on my car and lost 2x Bank 2 02s within the first 200 miles. Someone on the 2011+ coyote page suggested wrapping the headers and now, 600 miles later, I have not had an issue. The long tubes/sensors are exposed to a lot more air flow compared to the stock manifolds and it seems the constant cooling is overworking the heating element in the sensor. Mine would throw a bank 2 fuel trim code and surge very bad at idle. During part throttle and WOT, the sensor would work fine(datalog confirmed) but at idle, the fuel trims would go all the way to .65-.7 on bank 2. It's not super pretty but it seems to do the trick..
