Injector troubles really need help

I have a 2008 F450 6.4. 1st I got a Code P1552. Which from what I understand is Injector 2 problem. (If I would let the truck idle for a while before driving it it would do ok) So I had my mechanic Changed all the injectors on the Driverside please those little fuel lines and the Wiring harness for the injectors under the valve cover. I thought since he was going to be in there change them all and the fuel lines and the wiring harness. I ran great for about 2 weeks. Now I am getting a P0202 and letting it idle dont work. What is the difference between P1552 and P0202. Also Can I change the Wiring Harness from the ficm to the injector harness on the driver side only. The funny thing is when it is idling bad if I clear the code while it is idling using my edge monitor it starts idling right but then if I drive it it instantly starts messing up again. and clearing the code while driving it does not fix it at all.

So lets recap, you changed all injectors and fuel lines and wiring for the injectors on one side. The drivers side.

Did your mechanic use IDS or something similar and update the PCM with the new injector codes and put those new labels in place of the old ones ontop the CCV?
