I was at work comparing my 04 Xfire to a friends 04 C230 when I began to explain the airbox to him. So I showed him the airbox, how it works, and that was the end of that....the next day as I went to lunch I came to a stop light and noticed my car had a rough idle. The panic that came across my face was almost instant, but then I realized I'd just put a quick search on the site to see what some common problems are. I would have never thought that I didn't latch down the airbox properly (seeing as how I've removed it many of times now). Thank you again crossfire forum and you're helpful members for helping me narrow down this simple problem!

Now to just fix the TPMS system since I have aftermarket wheels and not the original stems anymore...currently doing the black tape method!
