I have a factory turbo 7.3 idi and the entire truck shakes between 1000 and 1500 rpms. It feels like its loping at idle and clears up above 1500 rpm. No smoke. Cracked fuel lines at each injector and idle changed on all of them. Going to have injectors pop tested by diesel shop, just wondering if I'm going in the right direction or not. Thought it was the harmonic balance but not noticing any wobble in it. Any assistance would be appreciated.
