Quick update. I haven't been able to get my hands on a scan tool to shut the injectors off individually to test them. But... When I burnt a hole in a piston, it was my #2 cylinder. Since then I have swapped my #2 and #6 injector when I was making sure that it wasn't a lifted injector problem instead of a hurt motor. My #6 is what injector I suspect to be sticking based off balance rates, it's still in spec but is the most out of balance injector.

that doesnt pin point this anymore. if you really feel its a stuck injector, you need to test like i said before to be sure. otherwise your shooting in the dark. you also need to take main fuel rate into consideration when checking balance rates.
