Ok, so now that you changed the plugs, your onto replacing the ignition coil on Cylinder #1. That's the part that sits on top of the spark plug.

Most misfires in Dodge/Chrysler vehicles are caused one of the four: Spark plugs, ignition coils, fuel injectors or hydraulic lifters and rocker arms. My experience with these vehicles show that your must run your diagnostics in the following order. Check the spark on each spark plug. If all spark plugs have a spark, then this eliminates spark plugs and ignition coils. However, if one spark plug does not spark, then swap its position with a known working spark plug. If swapping shows the working spark plug gets the spark, then change the defective spark plug, otherwise if the swapped working spark plug does not spark, then it is the ignition coil that needs to be changed. If all sparks plugs and ignition coils are working perfectly, then the next move is to shift positions of the injector from one of the misfiring cylinder with an injector with a firing cylinder. If the misfire moves with the injector, then the answer is obvious, however if the misfire remains on the same cylinder then you have to open the valve cover and inspect the valve lifters, one of them my be dead or one of the rocker arms to the cylinder may have flown off
