I have the head off my engine at the moment and figured it's a good time to test my injectors. I bought one of those bench mount pump type injection testers. Very easy to use and setup.
5 of my 6 injectors open at 1875-ish PSI. One of them doesn't open until 2250 PSI. This could be part of my rough idle problem. Is there a way to adjust the opening pressure down?
I had these injectors rebuilt less than 20K miles ago. I'm very surprised there is such a difference. (I didn't own the injector tester when I had them rebuilt otherwise I might have caught this problem if it existed back then.)
I need to check the FSM to see what the opening pressure is supposed to be set at for the H diesel.
