2003 EGR location?

I have a 2003 S-10 Blazer that has developed an off idle ping/rattle, truck only has 13,000 miles. Possible EGR problem, I filled it with 91 octane and marvel mystery oil seemed to help a little. On a cold engine can pull away without noise, noticable when warmed up. Any suggestions? It's not terribly bad, and only when starting out in first gear, no noise when going up a hill at speed. Is this acceptable?
