Did you put in new plugs at any point? Cleaning plugs will never give the same results as replacing them with new ones($24.00) at Oreillys and doing the deflood procedure before reinstalling them.

If that isnt the problem it seems like an injector issue, could have one stuck open. I recently fought a similar situation with some injectors I had cleaned and flow tested. But in a known good used set and the car acted 1000 times better and stopped fouling plugs and stopped bucking under decel.
