Anyone ever had a wideband read wrong?

Just curious. I installed a new oxygen sensor on my aem wideband because the old one failed a few weeks ago. I had the car tuned to run between 12 and 13-1, and now my afr is reading richer than 10-1 anytime I get on the gas.
It's reading normally at idle though, so I'm not sure if something changed in my car or if it's just a bad sensor. Any opinions or suggestions?

Sure. I've had sensors go bad and give kinda bogus
readings before. I've had the EIO and wideband set
to transfer functions that disagree. Tailpipe mounted
wideband readings can vary like crazy.
But you can't rule out other causes of WOT fueling
drift either.
