[Belmont dodge]

I have a 2012 durango SXT , 3.6 v6, 154,000 miles.
Can't find the problem. Getting codes P0301, one time, next time get code P0305, back and forth. Have replaced ignition coils, new plugs, compression test is good, car runs great. Any ideas?

Princess 's Mercury Milan threw the P0305...
ended up being a problem with the fifth fuel injector.
Ford diagnosed and fixed it for a fair price.
Wonder if Chevron or another fuel treatment could clear that symptom.
