OKay...so I am pulling up to a stoplight and just after I stop, my car stalls/shuts off. It's an automatic 2000 323i. I start it up again and it's business as usually. Later that day, pulling into a parking stall, same thing happens. A few hours later, the service engine soon light goes on. I have an appointment with service this week, but was just wondering if anyone has had this problem before?
