2003 Caravan idles rough and hesitates from a stop

[davehun]

This started about 3 weeks ago when it got extremely cold. It has warmed up and is still hesitating and idling rough. The engine light is on from a exhaust code, will get auto zone to tell me tonight the correct number. Otherwise, the van runs well once it is past about 5 mph. 3.3 Liter 6 cylinder

You need to find out what the code is . could be a bad plug or plug wire.
