With the lower temps here I have a small issue that has poppped up. When I start my truck in the morning if I just let it idle its fine. If I use my high idle tune or my AIC to bump up the idle speed, it sounds like its missing and shakes. No codes, I haven't had time to do a CCT or anything else. I haven't retorqued my injectors since installing them roughly 3k ago so I might try that. Any other suggestions?
