Dpfe?

I copied the following from a different post. It's exactly what my truck does. What is a DPFE? I'll try unplugging the vacuum line from the EGR valve and see what that does.





Is this a stuttering while maintaining a steady speed, just barely on the throttle?

Could be EGR. Pull the vaccuum line off the EGR valve and plug the line.

Drive it for a day or so like that; ignore the CEL that results.

I've seen a "going bad" DPFE cause that. Feels like trailer-hitching, as though you are pressing/releasing the gas pedal faster than humanly possible. Goes away completely at WOT (floored gas pedal).
