First Signs

I can't pinpoint a specific date that I first noticed any symptoms. I bought the Sunfire in the fall of 2007, and it was gone by February 2008. I think I first noticed the shaking in my lower leg while driving the Sunfire. It was just in my leg, and I only noticed while driving. I started to rest my leg against the console to keep it from shaking.
The shaking would come and go without warning.
