I have a 96 gt with a 97 crown Vic motor I think it was running fine all week n I decided to switch out the blue injectors to the orange injectors bc that is wat was in the old mustang motor n when I started it it made a pop noise n it didn't run right so I put the blue injectors back in it n now it sounds like it dropped a valve or missing on some cylinders could anybody help thinks

Record a video and post it.

You installed different injectors without changing the fuel map within the tune. Shouldn't cause valvetrain damage that easily though.
