CEL 71-74. obd2 ecu w/ obd1 clips and injectors?

Ok heres the story. I had obd0 injector clips with dsm injectors. Im now going back to stock so i bought some obd1 injectors to plug in. Now when i have the obd2a p72 it throws a CEL 71-74, misfire? But when i put my obd1 p72 in, it throws no codes. I want to run the obd2 p72, but im not sure whats causing the CEL. Is it the clips?

TIA

So you really can't say the misfiring goes away with that ECU.
