You should try reading the codes first before doing anything. After that try a tune up, rotor, cap plugs and cables. also i would recommend some insulators over the wires as they arc all over the place in wet weather. if you could I would shrink wrap all the wires for a nice tight dry fit. also try checking the trany fluid if it is low the trany can slip gears.
