I need to pick your brain about my pickup. It’s a 6.7L Cummins. When it’s cold or starting from zero it will often bog. As it accelerates it will gain lots of power but throw a ****load of black smoke. It has been very decent on fuel and not throwing me any codes to check. I have changed oil and oil filter, fuel filter and crankcase filter. Have also run seafoam in the oil and in the fuel as well as injector cleaner in the fuel. There was a slight improvement with all that but still having issues.
Any ideas or suggestions?????
