For the past month or so my car has had trouble idling it seems. My car runs fine until its time to slow the car down or come to a stop. When i bring my car to a stop, i feel the car start to shake pretty bad. And it sounds like it's trying to idle, but then it will rev up slightly and start the process again. I'm not sure if the clutch isn't disengaging or what but it doesn't sound or feel good.
