Try cleaning your EGR valve or at best replacing it, if it's too dirty with Carbon build up. The EGR pin may not be closing the valve 100% causing your issues and wont hurt to check all your vacuum lines also.

The EGR valve is located behind the throttle body on the intake manifold and would not hurt also if you gave the Sierra a Seafoam treatment to clean out all the carbon build up in your upper intake manifold.

Good luck and keep us posted. http://www.seafoamsales.com/
