Engine Code P0352 cylinder 2 misfire?

I have this vehicle I’m working on, and I can’t seem to figure out the problem, it has a misfire on cylinder number 2. Spark plugs and coil pack was replaced, and it seemed to help a little but after you drive it some bit the misfire code come back on. I tried disconnecting all the coil pack one by one to test them and it seems to at when you disconnect coil pack on cylinder number 2 the engine doesn’t seem to hesitate when unplugging it but if you unplug the rest of them the engine hesitates a little but before I plug it back in. Any feedback back would be great.
