You can connect a pressure tester where the fuel line goes into fuel filter, Make sure you clamp the hose to the line and tester before turning key on. You should have 45-50 pounds pressure, If not? replace pump

there are a couple of things, first make sure there are not restriction in the exhaust, i know the dealer has had to replace converters under warranty because of this problem, then theres a reflesh program for the computer due to this problem, and lastly,run with egr off make sure it clean of carbon,carbon gets stuck in pintle sets check eng lightbut carbon then blows by so when you remove egr you see nothing, well start with these good luck.
