The Fords seem to have a DPFE problem, although I would jump to that. What code is now showing?

What is a DPFE problem? I haven't had it checked again yet I figured I would take it to a Ford dealer and have them check it out. I originaly had taken it to Oreiley's auto parts. Don't know if I trust them now.

If it's a P0401 clean the port under the EGR all the way thru to the throttle bore, I use a steel coathanger. Clear the codes, if light comes back on replace the EGR position sensor.
