I have been fighting a PO341 code and missfire codes for bank 1. I removed the cam cover again yesterday and found that the timing appears to be 1/2 link out. I set the engine to TDC cyl1 and the dots on the camshaft line up with the bright links on 1 cam only, the other cam is 1/2 link out. I recently changed the varia cam solenoid as it was not working and unfortunetly did not notice the timing was out.
Hopefully the malfunctioning solenoid was the cause.??
