I'm back!
OK... still getting occasional rough idle with a P0344 code now (which is annoying because I didn't get this code until I had changed the intake camshaft position sensor).
P0344 throws and then shortly after, P0011 and P0016 and misfires on cylinders 3, 4, 5 and 6 occasionally accompany the P0011 and P0016.
So, I logged the data on camshaft setpoint and position and engine load on a good run (first chart) and then on one where the symptoms started happening (second chart), both during a single trip.
Choices seem to be:
1) troubleshoot a stuck solenoid valve
2) troubleshoot a wiring/circuit issue
3) troubleshoot a failing intake camshaft position sensor (unlikely as I just replaced this)
Thoughts??
