You might check your O2 sensors

 

driving drunk = no-no

 

Bad Karma and Bad Juju

Crawl up under the car and see what's bent up before asking.

 

Have the car scanned to see what code it's throwing.

 

Might have crushed the cat or broken something under there. Maybe the exhaust broke loose.. I'd look under there and make sure everything is still connected...like Harley-Davidson88 said, check your 02 Sensors..
