Good afternoon,

The Ford 6.0l diesel is arguably the worst Ford vehicle ever to perform repairs on.

The best, ***** ***** conclusive way to diagnose this would be with a scan tool capable of performing a power balance test. The scan tool will test each cylinder and then return data about which cylinders are contributing to misfire data or which cylinders are underperforming.

The only other method that might give a general idea would be to listen to the sound of each injector with a mechanic's stethoscope. A bad injector might sound slightly different from a good injector.

Have you had it scanned for trouble codes yet?

No. Thats what i was trying to forego
Ford Mechanic: Jared D, ASE Certified Technician replied 1 month ago

If the check engine light is on it might have stored a trouble code or two already. Most parts stores will scan those codes for free. If the injector is completely failed it could have set a code that might point you to the exact cylinder in question.

Ok. Thanks.. all done
Ford Mechanic: Jared D, ASE Certified Technician replied 1 month ago

Please let me know if you need additional info. I can help you nail down the problem later on if you are able to get it scanned. I have a fleet of these trucks so I've seen my fair share of bad injectors.

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
