Thanks for the information. Egr valves are very common problem. You would not wont to unplug it, because it would throw a code and derate engine at times. You can replace it yourself, it is not very tough job. Here is picture of it, it is on frontside of egr cooler. It is callout 43 in the picture. graphic

 

 

Loosen the v-band clamp connecting the EGR valve to the exhaust manifold.
