its the round valve which sits above the manifold, but also includes the fan an that in front of the battery
no its not, that the combination valve and secondary air injection pump. the egr is UNDER the inlet manifold, its held on with 3 torx bolts and is a pain to get to, my advise is to remove the throttlbody assembly and give it a good clean out, mine was crudded up and being jerky and that was only on 52K when i pulled it out.
