How did they "check the fuel injectors" - like with codes, or actually pulling them out? Misfire could theoretically be coil, plug, or injector.
Doing things one by one isnt unreasonable generally speaking, but it sounds like they are just throwing parts at the car (maybe just based on a DME code) without actually confirming issues. I am not there though... so maybe they are, but it seems strange that they seem to be chasing their tail fixing one thing only to have another pop up.
How many miles are on the car? Are you comfortable with DIY? If its high mileage and you are, it probably would be most cost effective to just DIY the injectors, coils, and plugs if you are convinced that is the issue. It would likely cost less than having them fix a few random coils and injectors, then you have old parts mixed with new parts and if they really are failing the others could go in the near future.
