so about 2 months ago, i installed berks rtp and ended up getting numerous o2 sensor codes, yes i torqued the bolts and yes the codes are still there, i have about 10 or so codes and some of them are in the ecu as permanent codes now
codes are p0037 p0057 p1148 p1168
p0130 p0150 p0031 p0051

i plan on getting a tune but want to deal with the codes first
any help is very much appreciated
