remove the intake hose and the exhaust port screwed into the egr valve, the remove the two retaining bolts from the intake and clean any old gasket material away. if possible run a piece of wire down the hole to make certain the passage is clear of carbon build up

It could be that your EGR valve has failed or has a piece of carbon stuck in it .

Depends on the year. Here is a site that has pictures of an EGR valve for a 1997 - 1999 Suburban: http://www.racepages.com/products/?D=gmc+suburban+egr+valve&Nty=1&Ntx=mode+matchallpartial&Ntk=Main&N=4294950670+4294963366+9926&Dx=mode+matchallpartial&Ntt=gmc+suburban+egr+valve Go to www.racepages.com and search for an EGR valve for your year rig.

The EGR valve is located in the center of the intake, at the front of the engine, between the alternator and the A/C compressor. I've added a picture of the location to the links on the right. It is titled "Picture of EGR valve location, on 1996 - 2001 4.3L (262c.i.) Vortec V6 engines"
