I think I will go ahead and change the EGR Valve. It was acting a little funny while I was testing it.

Define "acting a little funny"?

EGR valves pretty much work or don't work. A blown diaphram is the most common failure in my experience & that's easy to diagnose (won't hold vacuum) so I assume you've checked that. Sometimes they get a carbon buildup & sometimes the plumbing to them does, so if it holds vacuum take things apart far enough to rule that out, but replacing the EGR if it hasn't failed is a waste of time & $.
