low/ rough idle

I'm thinking of a transmission problem involving the torque converter clutch being applied when it shouldn't be. Seems unlikely but it's possible. Take it to a Dodge/Chrysler specialist or maybe run it by a transmission shop, they may have seen it before and you could cut to the chase.

I had a similar problem. Codes indicated oxy2 sensors .replaced both and problem solved

sounds like some transmission problem. Dakotas like my 98 have transmission, differential speed sensor issues, transmission pan/fluid and oil pan gunk, weak transmission pump, I also learned tonight that rerouting the spark plug wires and ignition coil wires can help the engine run right. there is a know short or surge that happens to dakotas in the wires somewhere. Also the ignition coil is mounted on side of engine and gets wet over and over then the windings get loose fray and short.. inspect your ignition coil, distributor plate.. also oil has been said to get into distributor
