On a 6.0 will one bad injector cause a rough running engine or will the other 7 hide the imbalance......Thanks

When a friend of mine had a bad injector, it ran rough and sounded like a 7.3

You would be amazed at how bad it will run with one bad injector.

Cold running is more with the spools.

Run the AE Contribution Balance on a hot engine to find internal injector issues.

Well your right about that Bullitt .I had enough of the missing I scanned with AE and #3,6 and 8 were missing.I went to a local shop and he GAVE me a bottle additive to try and low and behold 6 and 8 cleared right up.#3 was still bad so I pulled injector and removed spool valve and it was really tacky.I was able to pick it up with one finger.Cleaned it off with scotch brite and alcohol and reinstalled .Problem gone.
