Default Injectors and Vacume Question??

i have some sort of a vacuum issue with my 96 lt1. i think its vacuum because if im driving and stop my rpms will jump up and down 500 or so then drop down to 400 when i stop all the way then it will die or go back up to 750. i have ford 30lb injectors and they seam like they are not in all of the way, could that create a vacuum leak?

Are there little o rings between the injectors and manifold on yours?

not sure what your saying... there are two, one for the fuel rails and one that seems like it should sit inside the manifold. my problem if it is a problem is that i can see the o-ring.

Did you get reprogramming for your 30# injectors, and have you monitored your IAC counts?
