Hello!

I have a 2002 Subaru WRX sedan. A few weeks ago it got really cold and snowed here, below freezing, which isn't usual for my area. The car handles like a champ in snow, so no problems there.

I spent a few hours sledding with my son, and when I was leaving I started smelling gas.

I had the heat on and pulling air from the outside. The vents were pumping in gas fumes. When I turned the vents to recycled air, the gas smell wasn't increasing - it was only on external air. I thought it might be the car ahead of me, but when I arrived home the car still smelled gassy. Raw gas, not exhaust. A quick test drive showed that again setting to external smelled like gas.

I checked under the hood and saw no visible leaks. A quick inspection under the car revealed no dripping fluids.

The gas smell cleared out and everything is working normally now, but I still think something went wrong and I'd like to know if I'm sitting on a potential problem. I just filled my gas tank, and it is one of the lowest MPGs that I've gotten (just under 19, I'm used to about 20-22).

Anyone have any ideas what might have happened?

Thanks!
