I have a 2012 Expedition. It used to sputter some times at about 1500 to 2000 rpm. Now it seems to be doing it much more often. It has 158000 miles Oil was recently changed. Does not throw a code. Any ideas? I see a some post that say COP ....I don't know what that is. I do the research since I have the time and my husband does the work. Thank you
