Car notices it is idling too low and stutters in an attempt to raise the RPMs. I actually had the car stall on me once. Car needs a certain amount of RPMs to maintain a healthy idle. In our cars (and most bimmers) it is between 600-700. If it didn't matter we would idle lower to reduce fuel consumption. Had a similar problem with the N54.
