Lambda issue

[18 Smoke]

I have Ngauge reading Bank1 & Bank2 Lambda. Yesterday, under WOT, Bank 2 went to 0.00. It’s been reading.82 to .84 just like Bank1. STFT looks good on both sides. Still adding timing. Am I losing an O2 sensor? It still seems to work and match Bank1 under normal driving. ????

Sometimes on my x4 it will display stft at 0.00 and I just unplug it, restart it and its fine. If it was reading lambda fine then during the wot pull went 0.00 I'm not sure what that means. Did you try another pull after with the same result? If it doesn't happen again I'd say it's just a software hiccup.

I’ll hit it again right after and same thing. It seems like if O2 was bad it wouldn’t work the rest of the time. I ordered a new O2 today. We’ll see what happens
