Thank you for the input, I hadn’t considered a harness issue. I had a guy who works on 7.3s tell me that he thought it had a bad valve. But he is also the one who told me it was likely bad injectors, which have been replaced with no changes (except in my wallet).

This is my first time posting... I have an early 1999 F350 7.3... I am having a difficult time diagnosing my problem... When I start the truck, it idles a little rough (rougher than typical 7.3), when I am driving it, it seems OK, even when towing, until I come to a stop, then it shakes all over...
