It could be many things without being able to experience the problem first hand or being able to do some basic diagnostic tests to check the ignition system or fuel pressure it is hard to say. It could be a bad spark plug or plug wires, I have replaced some fuel injectors on these Caravans but I have also seen a damaged wiring harness for the fuel injectors at the intake manifold at the passenger side of the engine. Wiggling the harness on both cars made the engine run poorly on the two Dodge Caravans I saw this problem on.
