I just pulled 12 DTC's off of my 2004 F-250 6.0 diesel. Most of the DTC's read "injector circuit low-cylinder 1-8" and a coupld read "cylinder _ - contribution/balance fault". What exactly am I looking at here? Are all injectors going bad a once or is it a computer problem? Help please!

 

Well, you could be having a FICM problem with regard to the circuit low codes.

As to the contribution/balance codes, those usually reflect an issue with the injector. Is your scanner AutoEnginuity or something that is more then just a scanner? You should be able to graph the injectors and be able to turn them off one by one and to see if it's under or over fueling. Do it seem like it's missing? Shaking at idle etc? Do you smell raw unburned diesel fuel out the exhaust?
