1991 F-250 7.3 NA zf5. Truck shakes like no other under 2000 RPM when its under throttle... over 2000 it smooths out pretty good. And it has no power until you get around 1800 RPM... Injectors? Hopefully
Or IP?

Where did the brass come from.
Like others have said, its a cylinder or two not running right because of no fuel, lack of fuel, or bad compression.
Mine did that when I had a couple leaking injector fuel lines. Anything under 2000rpm's would shake the truck. Idled like it was a big block with a REALLY big cam![]()
