    At 1500 rpm my truck shudders then it will go away when i let off fuel or if i down or up shift until it gets to 1500. Doesn’t always do it. I’ve replaced all fuel lines fuel pump. #2 injector fixed one iva injector wiring harness engine wire harness check valve on fuel rail. Truck has 930k original miles. If this is any consolation my fuel restrictions gauge always reads 5 (almost in red) I’ve changed filters (from cat or Baldwin) has anyone dealt with this
