Question about 2006 Ford F 350 Super Duty
Very common problem. EGR valves die on Powersmokes all the time. First, has anyone messed with your MAF recently? This can fool the PCM into thinking there is an EGR problem. If not, the valves are easy to replace; just a couple of 8mm bolts (10mm heads) hold the valve down, and it is on the top of the engine right in front of (IIRC) the oil filter. In any case, if you have the new one in your hand, it will be easy to recognize the old one on the top of your engine. You will need an extension for your socket and ratchet, and you may need to use 1/4" drive tools because the bolts are so close to the body of the EGR valve that a regular socket won't get close enough. Be sure to put a little vaseline on the o-rings of the new valve to keep them from snagging on the edges of the holes as you install the valve.
NOTE: Potential for big problems here. Has this truck been using coolant, or blowing white smoke out the tailpipe, or overpressurizing the degas bottle? If so, you may have a leaking EGR cooler. The time to check for this is when you have the EGR valve out; look down into the hole it came out of - all the way down to the bottom - and see if it is wet in there. It will be sooty. This is normal. It may be oily; this is tolerable. Wet - with water or coolant - indicates a big problem that the dealer may fix for you for free.

Testimonial: "thanks your the frist one to back up my thinking, i did replace the air intake with a AFE stage2 that most be the problem!!"
Woops your not following Fords warning on changing the antifreze and not using the wrong kind. Ford might fis it under the emissions warrentee. But in these days of slow new car sales, Edgy warrentee work sometimes is going customer pay.
