Message	3rd time at track, 3rd time I've had the rear left bank code for the O2 sensor trip. Reset it and all is fine and I drive my car several times a week. This is over a period of the last 8 months. Threw an EGR valve code as well today. Running 93 Octane, timing at 15 deg, stock boost, high flow SZ cat pipes, stock DP's for now. Replaced that rear O2 sensor when I did the exhaust because it was seized. Used an Advance Auto Parts Bosch sensor with lifetime warranty. My thinking is that when running hard at the track the OBDII system senses higher Nox levels and therefore throws a code since I'm "damaging" the environment. Not sure what to make of it and maybe I'm off base, just not sure what to do at this point. 1996 TT #61 of 300
