Injector o-ring question

[srtkiller]

I have RC 550 injectors and when I installed them I used all new o-rings and grommets. Now the injectors are very loose and twist very freelI was wondering if this could be causing the car to stutter under mid to full throttle. I checked for boost leaks and everything is good this is the last place I think I could be getting any form of leak.Thank you.

It`s ok for the injectors to turn freely when installed. As long as there are no boost or fuel leaks, they are properly sealed, & should not be the cause of a tuning problem . . .

What are your AFR readings when it studders. Runnign too rich will cause that, and will fouled out plugs and or wires among other things.
As far as the boost leaks at the injectors, I've had 2 leaks at the injectors from cracked injector insulators.

I'd say to do a boost leak test and check all your ignition components.
