Ford,01 mustang v6 running rough at idle and drive. Please help. Replaced a bunch, still can’t figure out issue.

my 2001 3.8 mustang runs rough. Sometimes it runs rough at idle, if it's not running rough at idle it will run rough when put into drive. There is a lack of power and sputtering with a miss when driven, most of the time. It was throwing a code for miss in cylinder 2. I changed the injector and it seemed to run somewhat better but a day later it feels to run the same as before. I have put all new plugs, wires, and a coil pack in. Put a new fuel filter and air filter in. Cleaned the MAF. Not sure what the issue is at all. Please help.
