must be DPFE night!
been dealing with a rough running engine after new plugs and general maint. Finally got the P0401 code - insufficient EGR flow. Pulled the EGR valve and it looks clean. Inlet port is a little pitted, but almost no carbon buildup. DPFE nipples look a little corroded.
98 E350 van, 95Kmiles. I'm thinking its the DPFE too. Unfortunately, its 9:30 at night, no stores open and the van is all pulled apart in my driveway.
Oye.

The aftermarket ones aren't reliable. Use Ford only. Order it through an online discount Ford Dealer.
