What kind of injector probs do they have? The 6.4 I drive at work has an awful injector noise and 2 different dealerships say they cant find anything wrong with it.
Not seen an injector issue with a 6.4L yet,, it's been all 6.0Ls on the injectors. The 6.4 is common rail so the injection system is not all that different from ours. can only be so many things wrong with it.
