Possible to switch the plug wires on the coils to see if it is a bad coil? If not the coil, then switch the plugs.

so....time for some help, please.  My 1500 has started running really rough and misfiring on the rear cylinder.  Has new plugs, new air filter and I only run premium non-ethanol fuel.  it has slowly become worse to the point that it is no longer feasible to ride.  I put a brand new battery in today and resealed the air-cleaner mounting plate....still didn't help.  ran diagnostics...no codes flashed.....so...coils?. bad spark plug?  programmer going bad? ,  any ideas would be helpful....

thanks,

OR Seedman
