2005 Dodge Grand Caravan "sputtering"
Had check engine light read at Auto Zone after van began sputtering. It only said misfire in cylinder 3. Changed cylinder 3 buy it didn't fi the problem. Then changed all spark plugs, wires, coil pack, battery and used HEET. Still saying misfire in cylinder 3 and still "sputtering" at idle and when accelerating to try to get up to speed on interstate.
