Welcome from another recently "hatched" Eagle owner. This forum has plenty of info, and I've been saved already on my project by following the guidance of those that have come before us. Good luck with your project.
FYI, I took a look at your site. The thing you taped in place on your air cleaner is part of the TAC system, I believe. That vacuum motor controls a trap door that should close when the engine is not running, I assume to control escaping vapor. As long as it's open your car should run fine.
