I have noticed lately when stopped at a light and the ICE is running and then shuts down. the ICE shuts off with a shake or jolt. The car used to be very smooth and you could only tell the ICE shut down by the drop of the needle of the consumption meter. Although the rough shut down does not happen all the time it is much more frequent than before. I would like to know if others have experienced this or not. It may be the cold (winter)weather, but I really don't thinks so. Any input would be appreciated.
