Check and see if the EGR valve is leaking, to check this spray water on it at idle, if the water steams off the valve is leaking and is the source of your problem, also are you sure you hooked the new DPFE sensor up right? re-check it..

05 explorer. Rough idle, sluggish when accelerate. Replaced spark plugs, fuel filter nd egr value


You should check the fuel pressure and, if there is a check engine light, get the vehicle scanned for codes. The fuel pressure should run about 50 to 60 PSI when running and should hold pressure after the engine is off for a period of time.
