If I let the codes set at idle ... which is rough, I could clear them and then slowly raise the RPM's up to about 2600 when I heard the timing chain rattle. Reset the codes and was able to hold the RPM's steady at about 1850 without any misfires.
So, I would like some input on what to try next. Idle at engine full temperature is rough due to the misfire detections ... but at cold startup idle is good until secondary air timeout. Able to hold RPM's up with no misfires.
What do you guys think?

P0341 is as you know cam position sensor1: signal implausible/implausible operating range/malfunction.
You stated that you tested it.
Did you test to see if signal is getting back to the DME over the entire operating range?
If everything tests good with the Cam position sensor and wiring then I would look at Camshaft deviation and Camshaft timing on bank one.
