Hey everyone, first post on here! Had a problem while driving today and need some advice. I noticed a really strong/bad smell after going up and down a hill/incline multiple times in my crossfire (07 base model). The best way I could describe the smell would be a mixture between something burning and roadkill (it made me a bit nauseous). I can't really tell if its coming from something under the hood or if its from the exhaust pipe.

I was teaching my brother how to drive a manual and was having him practice starting and stopping when going up a steep hill/incline. I had him do this about 10 times. It was after this when the smell started.

Now the smell occurs even while idling. I will start it up in the morning and see if it goes away. Does anyone have any suggestions on what it might be?
