So I thought I would share all the codes with everyone. As I get more information I will gladly share in case others experience the same issue. The active codes are P0340, P0365, P0390, P0345, C121C00. These are the sames as the last time before the suggested repair. I am thinking that the C121C00 code is causing most of the issues but I cannot be 100% percent positive. The repair was the camshaft phasers replaced on front and rear banks, VVT solenoid O-ring and other gaskets removed during the process.
