Hey Fstar1, you've probably long since fixed your EGR problem. If you havn't, from the syptoms you describe, it looks like the exhaust feed tube to the EGR assembly is plugged (with carbon), you can clean it out yourself by removing the EGR valve & spray carb cleaner down the feed tube to clear it out. The carburetor cleaner & gunk will just blow into the exhaust manifold, so it's no biggie. The stuff will burn off when you run the engine. I think the dealer charges around $100 for this procedure. G/luck
