If you are sure they are correct, then you can still test the EGR for proper operation, but I would lean towards a faulty DPFE unit sending signals that are out of range causing excessive and insufficient at the same time (though, they coul have easily happened apart from each other.. not ACTUALLY at the same time)
Like I stated. once you pull that green tube from the top of the EGR, suck on the nipple of the EGR.. (manually. with your mouth if you want!! ) The car should stumble and choke.
From there, test out the "small cracks" by spraying some carb starting spray in the area (careful not to let any spray enter in to the actual air filter, or the car will CERTAINLY stumble, obviously.. You don't want any false positives from that.
Then move on to the DPFE.
Location and removal/prices can be found by utilizing the search feature at the top of every page (next to "my home")
Just search under troubleshooting, and change your date range to "all" and the phrases to "and" (vice "entire phrase".. that would only find a result if it matched exactly...)
