DPFE could it be that easy?
I have recently bought a 01 edge 3.0 86K I was getting about 15 MPG.. I thought i should be getting around 20 or so. It was a little rough at idle so i thought a tune-up was what it needed. Then I pulled my trailer with it for the first time and the MPG went way down to about 10 and stayed there even after i parked the trailer.
Then came the tune-up. It has not helped but the mechanic did notice the the engine check light didn't come on turning the key to on. He thinks that someone took the bulb out. So he checked to codes. EGR and #2 misfire. He suggested replacing the DPFE sensor.
So my question is... Could it be that easy?
