P0014 is a cam phasing system fault.P0302 is a number 2 cylinder misfire.
If the desired and actual cam phase angle error exceeds its tolerance value for a certain amount of time, then DTC P0014 will set.
The problem is, that if the cam phasing system is trying to compensate for the misfire, you will get a fault for it.
So you should probably start diagnosing the misfire first. Have the spark plugs ever been replaced? If not, I would pull the #2 spark plug and see what it looks like. If it looks ok, then swap it with #3 cylinder and see if the active fault changes to P0303. If it does, then the plug is the problem. If it doesn't, then you will want to check the injector signal with a noid light and see if the injector is firing properly.
I would suspect either a spark plug or injector problem though.
Then again, I am not at the vehicle and only going by the information presented.
