    Hey guys I replaced the EGR and the p0401 came back on the car after a few days. It also has a ruff idle.. I got the EGR from Advance Auto Parts. Could it be defective? Any other ideas? Thanks for the help.

    I had the same problem and bought an EGR from advance. When I swapped it for a Motorcraft part, the code went away.
