I agree. I am leaning toward injector issues. They have unknown miles. Weather is improving so I will roll with it for now. Also our winters have not been getting any colder than recently the last couple of years. I have been collecting Alliant and or Navistar new large B code split shots when they are found at a good price to duplicate these injectors with New sticks and possibly flow them or build a bench. Even starting with New injectors and duplicating these sticks would be better than starting with cores that had broken nozzles and not even touching the oil sides. On the good side of things when they are running good they run very well better fuel pressure and a better turbo isn't going to hurt as well. I may even tear down my AAs to build and try hybrids some other day down the road. Overall I am suprised these injectors run as well as they do while it's more luck than doing it right. I do want to build a bench but there is quite a bit involved and even building one isn't going to be cheap. Motor, pumps, lines, machining, materials and all that time and labor is quite a bit to build your own bench and then to setup all the electronics to fire the injectors correctly.
