What is this part?
 

I have a 2006 Saab 9-3 turbo convertible (manual). I found this spring on the floor driver side next to the gas pedal. It is about 5" long and I have no idea what it is. Everything seems to be running. All the pedals seem to be functioning as well (gas, brake, clutch). I was wondering if anyone has a clue as to what it might be from?

Thanks for any guidance.
