P0304 code help

[kam84]

I switched all my coils and sparks plugs and keep getting P0304 code. I also switch coil 4 to coil 1 and got the P0304 code. The car started misfiring and got the flashing engine warning. Need so help with this.

By switch you mean replace with new ones right?

No switched the fourth to the first coil and still got the code. By the way before putting all 4 brand new coils I had multiple misfire codes.
