The random misfire code (P0300) means that misfire (in this case #7) is random ie: it does not misfire every time. It does not neccessarily mean random cylinders are misfiring. The misfire is random. When you see misfires as high as #7, that cylinder has a problem.
P0307 would mean that #7 is dead, misfires every time.

I then commented saying maf could be a problem because the only info i had said it a random miss over all cylinders.
post 3. He further clarifies that its number 7 specifically.
Now my posts after that are reflecting the new info. My point is: try swapping the #7 coil with say the cylinder #1 coil and see if the misfires move from cylinder 7 to cylinder 1. If they do its a coil pack. If not, then its either something on the tuning/timing part of the coil circuit or a faulty injector or improper injector signaling
