2014 Mustang GT / Copperhead with (currently) a FSFD2AA strategy. Also saw it with my FSFD2AT strategy before I switched.
I've recently noticed that on a very intermittent basis, my widebands seem to be dropping to zero, for only a few milliseconds each time.
Nothing else appears to be impacted.
These are the original O2s in the car. I have already ordered replacements. But I don't believe that it's actually the O2s as I would find it suspicious that both would be exhibiting the exact same issue. Usually, when there is the same presentation on multiple devices, then the problem is someplace common to the respective devices. Nonetheless, replacing the O2s is not a bad idea given that they're originals from 2014 to the best of my knowledge.
These random/intermittent drops go all the way back to my very first log with VCM Scanner.
