major problem with ecu cel help fast

[boostedgst2984]

i have a big problem i have this cel light p0204 Injector No.4 output driver not responding properly i was running fine. I did the magnusmotorsports mod to get rid of the cel for my 6bolt swap and car ran shitty when i did it so i returned it back to stock and still shitty. I unplued the ecu for hour to reset and still shitty. The engine bogs down. And bad idle. What do i do to fix this
