Car just started doing this yesterday, during/after I hit WOT it seemingly keeps dumping fuel for a brief moment to where the car almost shuts off, then clears up. Idles and free revs fine. In the log you can see me blip the throttle up to about 3500 rpm, AFR hit ~11.5, it bogs down as rpms drop then keeps pumping fuel until AFR is ~8.5 then I killed the car.

Nothing on the car has changed except the plugs since I fouled them pretty bad yesterday.

I know tunes don't change overnight and it's probably mechanical, but I figured I could start here. If the attached file is too hard to read I can send an excel file.
