I would suspect one of two faults - either the oil control valve is stuck on or the actuator on the end of the intake cam is not returning to the rest position at idle. The result would be way too much overlap at idle-hence the poor idle quality. I've seen this with Hondas. We had a bunch of bad VTC actuators which would not move freely on the end of the cam. The only other thing that could set that code is a stretched timing chain - highly unlikely.
