Strange Beeping with CEL on
 

I drove around tonight, got a couple races in while I was at it. Then pulled over to talk to some of my buddies, i left my car on while we were talking. After around 10 minutes or so of talking, my buddy was asking me why my car was beeping. I was thinking wtf? It's not my car. I went inside my car and sat down in it and sure enough there was a beep. It was more like an extended note than a beep, in intervals or 4 or 5 seconds. I shut the car off then started it back up and it stopped. Anyone encounter this yet? Oh yeah, I got spanked by a 350Z tonight :(
