One thing you might try, remove the camshaft position sensors (x2) and try cleaning them before re-installing. I have read posts where this cleared up the P0303 Misfire 3 error. These sensors are located at the right end of the valve cover as you look at the engine.

One thing that I noticed when removing the spark plugs was that the one from what I assume is cylinder 3 had a lot of oil on the threads when I pulled it out. Does anyone have any ideas for what my issue might be? Appreciate any help or advice I can get. Hope to be back motoring soon. Thanks.
Did you try moving the coil to see if the error code changes?
You may need to replace the valve cover gasket set to stop the oil getting into the plug well....
