Ford has problem with the DPFE sensor. It monitor egr flow. Manually ck your egr with a vaccum pump and if it works normally then just replace your dpfe sensor

DPFE sensor??? Which one is it???? A picture would be great!!!!!

The DPFE sensor sits near the firewall on the driver's side behind the throttle body. It has two rubber tubes (from the EGR tube) connected to it. It is a flow meter (measures the differential pressure across a little orifice). There is a regulator valve on the other side of the bracket that holds the DPFE.

Hope this helps.
