Update - After a quick run to the store for a code scanner, I found a P0305. Misfire in cylinder 5. Guess I will need to pull that plug back out and see what is going on.

So....which one is 5??

Im not sure which is five but its likely that the reason you're getting a misfire is that #5 cyclindar coil pack plug isnt installed correctly.. check the connector and make sure it is snapped all the way in.

I had the same problem after changing spark plugs for the first time.
The cable on one of the spark plugs wasn't "snapped in".
After checking I found that on 3 out of 6 cylinders the cable was kind-a loose, so better check all of them

5 is the middle cylinder on the left side of the car (as you are sitting down in the car). 4, 5, 6 from front of engine to flywheel.
