Truck vibrating sometimes when jakes are on

[Shokar92]

Hi Rawze so after washing the engine and cleaning everything by hand, I noticed that the injector tube on injector 4 was leaking just a little tiny bit because I saw diesel around the area when the truck went to pick up a load and came back so I changed injector tube which I got from a local cummins dealer and the truck went on two 4000 mile round trips and the engine light went out by itself and no more Jake problem. I’m keeping an eye on it every trip to monitor if the Jake problem reoccurs. I hooked up insite I had to inactive codes for filter needs to be serviced which came up 4 times was done prior and again after I cleared codes and I had inactive code for fuel pressure low but valid that came up about 20 times everything's cleared and been cleared since so last two weeks and will update if anything changes
