Upon starting car - what rpm does your engine idle at (non cold-start)
I've noticed my idle rpm's dropping to about 600 rpm's when I first start my car. No problems driving it. I've had the car for about 2 months and started to notice the lower idling roughly about a month ago - it usually starts around 1000 rpms and gradually drops over the 30 seconds to 1 minute. The low idling is accompanied by a little vibration/rumbling.
If this is normal, then I apologize about the shitty post - but I didn't find anything that was this specific in any of my searchesz. This is my first 335.
