Default P0307 and P0357 ?????

The Search feature isn't working for me right now so I guess I will have to post this as a question.

Okay... Misfire Cylider #7.
Ignition Coil G Primary/Secondary Circuit Malfunction.

My car developed this problem yesterday morning on the way into work. The misfire isn't 100% of the time, more like 85%. When I got home I pulled the coil pack and swapped in brand new one for #7, simple right?
No.
The car started missing again and the same codes came right back up 5 minutes later... WTF!

I'm guessing wiring to the coil probably within the pack at this point. Tonight I am going to swap coil pack sides the see if it follows.

Any other ideas here?
What if the misfire stays at cylinder #7 after the packs are swapped?

Thanks!

Yup the wire appears fine. It's fairly new and doesn't look like it has rubbed or burned anywhere, the routing looks good. Maybe I will just swap it with one of my left over "extras" just to be on the safe side.

Thanks!

Anything else that might cause these codes and the misfire?
