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..

I would take it in and have them do a diagnostic on it, sounds like the cam shaft sensor to me.

Do you know if the plugs were changed, a bad or broken plug will also cause rough idle and slow acceleration?
The P1684 code simply means that the battery has been disconneted within the last 50 starts."
