I have seen a few that have had the front diff gears strip from the axle shaft splines. If it's got in time you will need new gears and an axle otherwise its a complete front diff rebuild

Question Answered: 

Yes. The intake valve doesn't seat properly causing a miss. I see it more when it's cold and extended idle. The only fix is to replace the cylinder head

Question Answered: 

Was there any other code besides the p0300? I have has issues with the camshaft position solenoid actuator valve. There are three screens on the valve and sometimes the screens move or actually break off which will effect the timing of the engine. The valve is located on the right side of the engine towards the front just next to the ac line. It's held in by a 10 mm bolt. Take the valve out and check the screens. Worth a shot.
