Heres the skinny,

Out of nowhere I decided to do a spark test. So I pulled the 4th non firing coil out and removed the rubber piece. Touched the valve cover and SPARK SPARK SPARK

So this brings me to believe that the spark plug might of been defective. I swap it out to cylinder 2 and put it back in. Upon removing and swapping the spark plugs I noticed that the 3 cylinders that were firing the plugs had massive carbon build up. Meaning the tips were black and dry

Then proceeded to check the injectors to check out everything and it checks out.

Checked wiring and continuity and works out.

So right now everything is working but the 4th cylinder isn't firing... why!?!!??!?!
