My Car is Misfiring Horribly. PLEASE HELP!!

OK so I installed the professional products typhoon intake manifold in my 06 m6. I also installed the svede speed intake. When I first installed the manifold there was a huge vacuum leak which got fixed. Now the major problem is the piston number 4 is misfiring. When we run the code it says that there is an open in the injector. Now I have no clue to what's that mean, but if somebody else does then please can you help. Also we would disconnect that injector while the engine was running to see if it would do anything and nothing would change. I've never had misfire problems until I installed the manifold. Can someone please help.

re

sounds like the O ring is not seated right for the injector I think it has to snap in then the fuel rail holds it in place----danfigg
