-Faulty ignition coils
-Intake air leak
-Ignition coil harness open or short
-Clogged or faulty injectors
-Injector harness open or short
-Insufficient cylinder compression
-Incorrect fuel pressure
More than like it is another faulty coil. You can try checking some of the other non costly items such as the intake air leak, ignition coil or injector harness faults (multimeter and FSM). But, I'm betting it is another ignition coil.

Air filter and Vacuum leaks are the first and easiest checks.
P0300 is random misfire. This can be just one cylinder, intermittently.
OR it can be multiple cylinders intermittently.
Because it's intermittent, the computer can't tell which Cylinder is mis-firing specifically.
You need to check for stuff that would affect the entire system before you point fingers at individual things like a coil pack when you have this code.
