If your not loosing coolant and it's not not wet around your rad cap I doubt that its head gaskets. Odd that your getting the P0487 code with an '05 as I was pretty sure that the throttle body crap ended in late '04 and only carried over to the '05 Excursions (GAWD I hate Ford for doing that), but anyway, loosen the clamp on the intercooler connection to the intake elbow and remove the four bolts on the intake elbow. Rotate it out of the way so you can remove the two Torx screws and remove the butterfly disk. Put everything back together. I'm thinking the EGR throttle is faulty. Take it for a test drive and see if it still does the same thing. As for the other codes I'm thinking there separate issues.
