I could understand the high flow cat causing a problem for the downstream sensor. Rarely is the upstream sensor a problem, it’s just used for closed loop fueling. You’re not running rich or lean are you? Check your O2 wires, make sure the header didn’t burn them anywhere

btw - wtf is p2aoo? is that nissan shit? I can’t find any info on it anywhere

yeah, it is bank 1 sensor 1 range performance…the wires are all fine, and i have two spacers on my 2nd o2 sensor now…
