I have a 07 6.0 that has 153k on it and of course with the cooler temps the truck has a very rough start up. Temp was about 28 degrees that night and she spit and sputtered for about 45 seconds and Once warm she starts and runs like a beauty! She has a performance tune on it with the X4 from previous owner and lift pump. I changed the oil recently and did the arch oil additive to help with any stiction. Problem still persists on cold starts. Batteries were from 2018 so I went ahead and replaced them. From what my 6.0 friends are telling me it sounds like injector(s). Should I go ahead and plan to do all or just ones that may have issues? It does have a slight miss at warm up but goes away. Any tips would help, thanks!
