What kind of injectors for what kind of car are you talking about joel?
I have seen quite a few CIS-injectors and they are all straight. Not bent in any way.
a rough idle could have multiple causes. It could be the injectors, if they are worn from using fuel other than good premium or other injection related parts. Try a fuel system cleaner like Slick 50
You could also have a bad oxygen sensor or collapsed motor mounts(usually the cause!).
