Whats Wrong: Car was running fine all day. Went to take my gf home and on the way back at a stop light I started getting a bit of a rough idle. Kind of felt like I was running out of gas but I had half a tank so I know that wasn't it. I took this video of it idling when I got home:

What do you guys think the problem is?
