Since this seems to be the problems section...

Whenever I rev my car to ~4k RPM or more, my CEL blinks at me. I got it to stay on long enough once to run to autozone and scan the code.

P0303: Cylinder 3 misfire

I changed the spark plug and reset the ECU. No obvious faults on the spark plug, except it looked slightly burnt out. At low RPM the light will not come on, but every once in awhile when I'm passing someone my CEL flashes again. :mconfused:

I'm assuming it's the same problem. My next step is to just outright replace the coilpack. Is this absolutely necessary?

switch coilpack with another cylinder then clear the code and go for a drive
