Hi..there thanks for your reply..

 

Ok..P1340 can cover two possible faults - the first being an ignition missfire detected on no4 cylinder " from i recall cylinder 4 will be the cylinder on flywheel side rear bank of cylinders" as you look into the engine bay" either a bad sparkplug/or pencil ignition coil or wiring to that coil so certainly check the plug connector for any wiring damage..you can try and swap over that no4 coil with another coil and then see if the fault code moves to another cylinder if it does then the coil would be the issue - The other fault this code can cover is malfunction on Circuit B of the Camshaft sensor

-either the camshaft sensor itself there will be two on this engine so check sensor for rear bank of cylinders /wiring fault between that sensor ecm..I do hope this helps
