Yep! Fuuuuunky!!!!!!! I have owned three 2004 Crossfire Coupes ... same funkatude in ALL three of them! I also noticed this smell coming from my Jeep Liberty right after I bought it. My friends said that I was the ONLY common denominator!!!! Shhhhhesh ... Then I pointed out that Chrysler and Jeep are one in the same! Anyway. The foul smell happens out of the blue, randomly, and it happens with both A/C and heater. GAG. It DOES smell exactly like a dead, decaying mouse, but I am sure it has to be something else. I will try the cabin filter thing. Thanks for the suggestions!
