I'm new here and learning about these particular engines, but I'll make a suggestion...
As somebody else suggested to me recently, you could swap components with another cylinder and see if the problem moves. First swap 6 & 7 COPs. If the problem moves to 6 - bad COP (even though it's new). If you still get 0307, swap the injectors and repeat.

I just fixed a misfire in#4 in my 5.4l and I found a small pebble worked it's way between the plug and the wall of the hole.Must have got knocked in there during the coil changes I tried to cure the misfire with.I used a small mirror to see into the cavity.You might want to check for that during your troubleshooting.
