I don't know if this is normal but:
When I stop the car and press the clutch, the RPMs drop down to just above the 500 RPM line for about a second and the car vibrates a little. Should I be worried?
Thanks.

It's a 2003 325Ci. It doesn't idle there. It just drops down for a sec and gets back to normal. It's the vibration I'm worried about.

the vibration is from the low RPMs. Get your idle circuit looked at. Does it always do that or only when cold/warm? The problem is that your car isn't transitioning into idle very smoothly.

I feel the vibration more when the car is cold. It vibrates when it's warm too but not as much. The vibration occurs for a second when the RPMs drop.
