I have an 01 7.3 that I have recently had injectors installed 200/30. Ever since then the truck has smoked more at start up. 15,000km on them now. I drove it to work the other day and it ran fine. A couple hours later I went out to start it and it took a little longer to start than normal it spit and sputtered then started. It was knocking so bad it sounded like a hammer baging around inside. I shut it off then started it again it knock like that for 30 sec while I was looking under the hood. Oh and smoke like a freight train. After 30sec the loud knock subsided and now sounds like a dead miss. Still smokes and has less power. Do you thing it digested a injector tip? Or any other suggestions?
