If that fails; take it to a speed shop and bend over

I have O2 spacers sitting around. What do you mean by A/F secondary O2 probes? The upstream O2 sensors?

I believe I have found the problem. I was lurking on the GT-R boards and this is a common thing for them. The cause is usually an exhaust leak

Found the problem and I'm slightly ashamed of it.

Sandwiched the gaskets with copper RTV and tightened the bolts to holy hell and no more codes

Sorry to revive this thread, but I'm having the same issue. Wondering if a leak could be the cause. How did you find the leak exactly?

I like to take the tube from a roll of paper towels, hold one end to my ear, and move the other end around until I find the source. Be careful when working around moving parts.

I just got these 2 codes myself (2096 and 2098)on my Infiniti qx70, I cleared it with OBd reader, but will look deeper into it this weekend.

Same setup, ark exhaust with test pipes
