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?
