extented starter turn over,1-2 minutes rough idle on 2003 Dodge Durango

on cold starts

Asked by for the 2003 Dodge Durango
It could be so many things depending on mileage and service history. Has the Durango had spark plugs or a tune up recently? Could it have a vacuum leak? Very hard to guess without being able to do some basic diagnostic tests or experience the problem first hand.Have seen injectors fail or get dirty on a few of those.
