Which injector is failing?
I had been experiencing some stalling lately, and had been presuming it was a HPO system leak.
However, we put a scanner on the truck today and the IPR duty cycle never went above 25-30%. Then we talked to a Ford tech (I don't know how 6.0 savvy he was) who thinks its an injector. He thinks the injector gets stuck open and allows air from compression into the fuel system. This would explain why my original post how that air was getting into the fuel bowl.
Do you think this is a possibility? If so, is there a way to identify which injector it is (other than with a scanner)? We have a Lotus scanner, but weren't able to find cylinder balance readings in it. They are probably there and we just couldn't find them, but if there's another way (i.e. unplug injectors one at a time) please let us know. TIA
