Running very rough

I hit what was left of a deer body on the road and later jacked up my car and spray cleaner on the undercarriage and scrubbed it with a push broom. I'm thinking I have the vacuum line off or something causing it to run so poorly. Almost like there is a bad miss or vacuum line issue. Also smells like it is burning very rich. When I'm sitting at a light the car will even shut off. Any ideas?

I tend to agree with you. However, these engines typically don't have vacuum lines exposed very well, especially on the undercarriage of the vehicle.

Here is how to test for a vacuum leak so let's do this and rule that out first:

The next thing you want to do is lay on the ground and look for any damage. Clearly if you just ran over a deer I wouldn't expect serious damage but hopefully we can find the general area that it hit and then look for components in that area that could cause this.

Let me know if you find any leaks and we can go from there. Lastly we are going to want to check for codes and see if that points us in the best direction.
