Fixed it. I replaces the fuel delivery copper washers again. Cleaned everything and did the correct torque procedure like I did last time. The idle miss is gone. I was sure it was cyl 2 because I could loosen the injector line and it would make the least difference at idle. I did not see any issue with the washer or any trash but it is fixed. It is nailing at idle now but hopefully that should quiet up in a few miles.
