I have a 85 6.2 with kind of a rough idle. It has a new fuel filter and i ran some power service through it with little help. Run fine going down to road with decent power and milage. If an injector pump was going out it would have low power and be missing all through the power band right? What about that little mechanical pump could that be it?
