Hey guys...I have a 2011 caravan crew. Just bought it at 26,000 miles from the dealer. I've noticed whenever it gets a cold start it has a somewhat rough idle, nothing too nasty but its definitely noticeable. When it starts from cold the rpms shoot up to about 1500 and slowly drop down back to 600 or so. Its about the 1100-1400 range where the rough idle is there. It only has this behavior while still in park with the cold start. Never does it in reverse or drive. Has anyone else experienced this or found a fix? What could it be? Any help would be appreciated. Thanks!!
