Started smelling gas while driving home from church on January 8, 2012. Smell of fumes intensified. Must roll down windows whenever driving. My eyes began to burn. I parked the car when I got home, and I could smell a lot of gas when I got out of the car. Car sat until Monday January 9, 2012. I still smelled gas. My car began burning extreme amount of gas. Car sat until the 13th. I filled up to a full tank of gas. I drove 7 miles to the store and 7 miles back. The car burned 1/8 tank of gas. Learned of 2005 chevy Impala recall due to fuel system/ fuel pressure regulator. Recall id# 64377. I contacted dealership. I drove home with the windows down in 19 degree weather. Now it is sitting again due to mechanic recommendation.
