Help with code H30F3

I've been searching for awhile on this site and Google and yet to find a clear answer to this code (H30F2). I do have some stumbling occationally so I believe it is probably a missfire in cylinder 2. Possibly bad plug or coil but wanted to make sure before ordering parts.

Any help would be greatly appreciated.

just change your coil #2 to another one and if misfire follows is most likely your coil.

I thought of that but would like to know what the code is before I disassemble everything. I will use that method to determine if the issue is the coil or plug. Just a little surprised I can't find this code.

Probably going to get all new plugs anyway as I've got about 30k on this set with a tune but really want to know if this is a misfire code.
