I was trying to get speed density lined up and my AFRatioEst went from smooth rolling valleys while driving and flat lines to sharp edges and when I do a pull they jumped all over the place. I have no idea whats going on or even where to begin to find the issue.

Any help is much appreciated. the one from 10 27-01shows that I was rich but no weird spiking. The 10 27-02 log shows crazy spiking at higher boost.
