4g63 on 3 cylinders

[gt35rx]

Well I finally fixed my car and got it running again. The problem is that the engine wont run smooth. It sounds and feels like its running on 3 cylinders. What can I do to correct this? It's a 95 x with a 6 bolt swap. I have C.O.P. 550 inj, 50 trim, evo 3 intake manifold and just got the block ringed. when I hold the acc above 3k or leave the throttle in one spot it will run smooth but when I try to give it gas or rev it up, it just falls on its face with 3 cyls. I checked everything and seems to be a injector problem with cyl #1. Before my car died, It would do the same thing and I would get out and ground cyl #1's inj with my test light and it would go back to normal. I tried to do that now and am going no where

Perhaps something is clogging the injector. Pull it off and take a look... should be pretty obvious. If it's full of crap, clean it out using the vfaq method.

pulled the inj to make sure they are clean.

Do you know what cylinder it is? Check the plugs and wires as well. I used to always have one spark plug that would turn itself loose on my car and cause my car to misfire.

do a pressure test, that would tell you what one it is.
