The crankshaft position sensor will cause a lot of grief when it is not working correctly. Most of the time, simply replacing the sensor fixes the problem. Sometimes replacing the wiring is necessary. It will cause very poor performance and economy across the board (I.E. - this problem needs to be fixed A.S.A.P. IMO). If your plugs are some platinum ones, I personally would change them to the factory plug. A set of four should run no more than $10. The part number is on the bottom of the hood on the sticker. These cars are picky about spark plugs. That will probably help too.
Also, stick with a Dodge sensor. The cars don't usually like the aftermarket cheapies.
