While I didn't read through the entire thing, this thread has a link that probably includes about everything you would ever need to know about the EGR valve: removal and re-installation, cleaning, etc.

Again, much obliged. I know little about these cars, but am not new to wrenching on cars overall. Had a Subaru Impreza WRX/STi for a few years and recently totaled my 99 E36 M3. Turning a wrench isn't new, but the first time doing things is still just as intimidating now as ever.
