When I stop at a traffic light for example, when the car is warm, my car idles at around 550-600 rpm, is that normal? It almost feels like it is to low because when I slow down to a halt, I get this vibration from the engine once it hits 550-600, anyone else experience this?

 

anybody?

 

Your kiddding right?

Look at what it idles all the time all M272 idle in the mid 500+ area...It should be smooth, if not call a dealer get an appt.

 

The idle speed is normal. What you could be feeling is the extremely subtle shift shock to 1st after fully stopped for more than a ~second.
