Hi,

I changed the spark plugs six months ago. after I got the error codes I changed the ignition coils and both camshaft sensors, and still getting those codes and the car idles hard, stalls.

Good afternoon,

The first thing I would do is to check the fuel pressure. The 300 codes could all be related to low fuel pressure.

The 1339 code is for the cam retard. It could be sludge in the valve for the solenoid to adjust the timing. I would change the oil and filter and add some seafoam to see if you can dislodge the debris in the valve.
