Oh one thing to look for, might be an isolated incident?, wife's Explorer (used what looks like the same DPFE sensor) I found it had yellowish goo oozing from one of the hose nipples when investigating the same problem with it. It caused a blockage at that nipple and was a clear sign of a dead DPFE sensor!
