I have a 2011 countryman with 80,000 on it. Had clutch replaces at 17,000. have had a "hard Knock" since getting it. recently hard time starting when cold, missing, rough, not starting. had spark plugs replaced at 60,000, 2 weeks ago had high pressure fuel pump replaced. 2 days ago rough missing and now power especially up hills. dealer said it is the number 4 injector. I asked could it be that high pressure fuel pump. or at least that caused this problem. You guess it no and the jib replacing all 4 injector would cost 1200. Any suggestions and or help


thanks
