I have a 2001 Dodge Gran Caravan Sport and u encountered the trouble code P0303 which indicates a misfire in cylinder 3. You need to check your ignition wire on 3, your spark plug on 3 and if need be, replace it or try to replace the others too and lastly if the trouble code is still there then you might replace the coil pack as well.
