My truck is running extremely rough. Starts bogging and misfiring majorly when moving. And sometimes when the miss gets so bad you here a tap or pop. Idle is ok. And doesn't affect anything when increasing rpm in neutral or park. Ive replaced the maf, air filter, plugs, wires, coils, egr valve, and the dpfe sensor. Did an oil change. All have less than 500 miles on them. Now there are a few codes coming up. (Shown in picture) I tested the vacuum on the egr valve and it made hardly any difference on the truck. But when reading the trim it does change the values when vacuum is applied. Does anyone have any idea what could be going on?
