Dodge Caravan Engine Problem

My 2002 dodge caravan battery was disconected for about 2 mo.
When I reconnected it and started it the engine would idle rough and surge when I accelerated. Does the computer have to
relearn?

The Engine Computer lost its memory and has to relearn "minimum throttle" before it will know when it must be in control of idle speed. It also might not give you the normal "idle flare-up" to 1500 rpm when you start the engine. To meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the brake or gas pedals.
