95 Eldorado rough operation. Changed plugs and wires with a little improvement. Don't have a manual for the car. Using Web OBD link Found code P119 "Open or Shorted Injector". No other P codes. Also noted that only plug #6 is wet. Resistance of the #6 injector is 12 ohms. What are the next steps to correct?
so you have a bad injector .. start to disconnect them ONE AT A TIME and which ever one DOESNT make a diffrence in the idle that is the injector at fault.
pull the fuel rail and be sure to relieve the pressure in the fuel rail by a valve at one end ( not sure on the 95 engine you should find it if you follow the fuel rail)
and then pull that injector see if its clogged etc etc. or test the circut.
if you beleive the injector is fine.. swap it out with another one and see if the misfire. moves to that cylinder or stays at the original one.
then obviously buy a new injector or look into where the wire has been screwed up.
