I have a family friend who works at ford ask someone. He's a mechanic for ford but is gunna ask one of the tech guys.

Also I have already replaced the DPFE. Rough idle at startup started when I got the motor put back in if I recall. I'll try and get time soon to check over the DPFE hoses though. I believe they run to the egr tube.
