vibration when cutting off car
when I turn the key to turn the car off, the car vibrates as it shuts down. I didn't notice this while test driving. It's not a harsh vibration, but I can just really feel the engine shutting down. I also get a slight vibration at idle. It's not a rough idle, but it is almost as if I am in a built big block, like, that kind of vibration. Any ideas what this might be?
It's an 02 with 50k miles.

A normal C5? Seriously, what you described is typical. The slight roughness in the idle was in my car when I took delivery in '99. I asked about it at the time and was told to learn to ignore it... I would imagine if it could have been removed the powertrain guys would have gotten rid of it before production. I believe the "vibration" felt as the engine makes the final few revs before coming to a stop is just dropping into the natural frequency range of the drivetrain. If you push in the clutch before turning off the ignition it won't do it.

haha. no ****. I still have a lot to learn about this car. I went from a Hyundai Tiburon to an 06 Mustang GT, and had to learn to drive that car. Now I traded in the Stang to this, and I feel like I am starting all over again. haha. Thanks for the info though.

Pretty sure he didn't need a step-by-step guide for shutting down the car in reverse.But yeah, just make sure the clutch is in when you power down and it shouldn't be bad. Sometimes I leave it in neutral when parking (only if the car is on level ground and I won't be away from it for long) and I still have the clutch depressed when killing it.
