TOP END REFINISHING - ZR-1 Net Registry Forums

FWIW...after I replaced my injectors and O2's my Datamaster file CL showed both banks long term trims to be pretty steady at 128/129 L-R. Short term varied slightly about 127-130 for a 15min idle run.
I can tell you that originally I had a bad primary fuel injector (6 ohms hot) (12 ohms cold) on the left bank that gave the same rich indication that you have on your right bank Lterm. I don't know if that helps or muddies the water more.

Without knowing the part number of your injectors its a hard guess if they are original or not but I will tell you my original injectors looked pretty much the same as yours in the pics. I think I mentioned this wayyyyy back in this thread. I would ohm the primaries out cold and hot and write them down.
