Answer 1

P0340 Camshaft position sensor circuit malfunction

This code can just be picking up the rough idle condition and not necessarily the cause of the rough idle.You will need to rule out a mechanical condition and a electrical condition you will need to test the connection of the camshaft position sensor for  its 12 volts.If that area is good a mechanical condition  within the valve train , a cylinder leak down test will help pin point the cause of this code
