Short term fuel trim is all over the place...-9% on low load, +4% on full throttle.

Negative fuel trim is telling you the car is adding less fuel because it is already too rich.
Is there a schrader test port on the rail? Check if your fuel pressure is holding.
I think this is a mechanical issue like a jacked injector pissing unwanted fuel in.
