my dodge caravan shutters at start up in morning or after sitting awhile. it has done this from day one? is this normal for this engine? only 1000 mile. once I start driving it is fine.

That does not sound normal at all. Does the tach move up and down while it shakes/shudders? Is there any sound?

when I start in morning tachometer goes to 2000rpm. It takes quite awhile to get down to 600rpm. On the way down tachometer does fluctuate a little. The shaking feels like a misfire.

Mine does the same and its two days old....hmmm Once its warmed up its smooth. Even if I sit in park and bring the RPMs up to where it runs cold starting and it doesn't do it.

My ram c/v 2012 with 16k has done this in the last 6k miles... Next oil change i am complaining since i noticed it starts to overheat and the coolant is actually low. Already had the trans pc flashed for the recall.
