    Sorry. 6pack again if you go back to dealer. I have had customers doing it twice in the same year. If you take to a shop with a sharp eyed tech, he will be able to tell which one is bad by pulling injectors and inspecting carefully. I have had some luck with pulling out, cleaning injectors and cups and re installing using Detroit Diesel graphite seals that were used for DDEC III-DDEC IV injectors.
