My question is, could this be related to the EGR system and if so what part is next to replace?
Any help is appreicated! Thanks!!
from your first post it seems as though you have an ATX. if it is maybe it is related to the tranny? also from what i have read the tranny is rev limited while in Park, i think 3500rpm?.
but if you meant neutral instead of Park then your tranny would not be an issue.
ohh and to clarify, the DPFE measures the pressure drop or delta pressure across a 2 inch section on the EGR pipe. this would not cause bucking when accelerating, it just makes sure that you have some vaccum or flow on that pipe. The egr opens up when decelerating so when the throttle body closes the engine will not feel like its choking.
someone can correct me if i am wrong here!
