Cylinder Misfire Issue
Check engine light comes on I check it with a reader and comes up P0305 number 5 cylinder misfire. Take it to the dealer, they say it is the PCM has to be ordered will take approx a week to get, maybe due to the New Year holiday. They install the PCM and problem not fixed. They then said it was the injector, replaced , still not fixed. It seems they should have started with the spark plugs then the coil pack then the injector for the number 5 cylinder before replacing the PCM. It has been 2 weeks and they still have the vehicle. 2013 Grand Cherokee 5.7 L 800 miles. Anyone else with the same issue?

Thanks, got the vehicle back and they said they messed up the wire when they replaced the injector. It appears it is fixed.
