When coming to a stop or when at a stop, my car would shake very hard as if it was going to turn off. Fortunately, it never has. I would have to put the car into neutral to stop the shaking or it would stop on it's own after 10-15 seconds. During this time, no lights have ever turned on to indicate there was a problem. The first time this happened was in late July 2009/ early August 2009 and ever since then, it would happen at least 2 times a day. My car has been in the shop multiple times for this issue.
