Here is another symptom maybe you can help me with ... I am still not quite sure how this variocam system works. When are the solenoids activated? Does the actuator float under oil pressure when the solenoid is not activated? The reason I ask is this ... I just unplugged bank1 solenoid and now I can rev and idle without the timing chain noise as I experienced earlier. But, I still have bank1 misfires on all cylinders without the P0341.

I'll probably swap coils this weekend to rule them out for the misfire.

I am guessing that the solenoids are active from engine on to about 2800 rpm's or when demand is high? I read somewhere about the basics of the variocam system, but nothing detail related to when it is active.

Thanks for the input ... it is always helpful to learn from others.
