Hey guys, I'd appreciate some help on this one 2004 Dodge Stratus, V6.

I ran my car on Sunday, about 8-10 trips to stores, etc, and everything was great.

I got in the car Monday morning, started it up, and it sounded like a truck, nasty exhaust sounds, smell of gasoline in the exhaust, and really rough idle. I haven't driven it anywhere since, and yesterday when I started it up, I noticed the CEL was on, and it sounded really bad, and was vibrating the whole car.

It has 46,000 on it.

Any ideas what it could be before I have it towed to the dealership? Any help would be really appreciated! I'm thinking it could be a sensor or something. I can't really think of anything else that would change overnight sitting in a parking spot that would cause it do act like that...

Any ideas?
