Hi my name is***** will be glad to try to help. If the injectors test good you will need to crack open the injector lines one at a time with the engine running and listen for the cylinder or cylinders with little to no change. This will be the problem cylinder. check for low compression and or metal in the filter or oil pan indicating rings or a piston/rod problem. Also check the valve adjustment or for any damage in the upper end or valve train with the valve cover removed. Let me know
