Well, I guess I should change the title of this Thread:
If you store your car for the winter, this could happen to you.
I just heard from Kevin (the technician working on my car) and he finally found the problem.
It turns out, the muffler was packed full of DOG FOOD!!
It seems that a mouse or mice took up residence in our garage and found the muffler of the Crossfire an excellent place to call home.
So if you store your car for winter, ya may want to "PLUG" those giant exhaust tips, because they must look like the Grand Entrance to an expensive "German" Spa and Resort.
One more thing, If you live anywhere within a 200 mile radius of Klaben Chrysler in Kent Ohio, and you need something repaired on your Crossfire, I don't think that you would be able to find a more dedicated, or expert technician than Kevin.
