Reading a spark plug

Not nearly as bad a teardown as my Supercharged 4.2, now if that MFer comes off it is getting new injectors.

I removed the top intake and swapped out number six injector with number 4 injector. Drove it 45 miles and check engine light came on . Code P0306 came back, cylinder 6 misfire. I have replaced spark plugs and swapped them around. Replaced coils and plug wires. I just swapped injectors. The code P0306 came back. Cylinder 6 has 146# compression. Anybody have an idea where to go from here?

That would be my guess as well. May try replacing the injector plug. You'll have to cut the wire and splice another connector on. I'd recommend using heat shrink crimps on the connections.
Beyond that you're looking at a deeper issue. Something further back in the wiring either on the injector side or the spark side, or an ECU issue. I don't think an ECU issue is likely.
Did you happen to do a visual inspection of the injector plug when you swapped them?
