Are you sure about the 0014?The 0300 just means that the engine is missing or has missed on more than one cylinder at the same time. Ignition coil failure is very common on these vehicle and that's where I would start.

Code P0014 is, Cam Phaser performance and Code P0300 is Engine Misfire Detected.

Okiee dookie, p0014 is actually a malfunction of the cam position actuator solonoid, which is on the passenger side of the block beside the power steering pump
