my car hesitates and loses power while driving. check engine light codes say cylinder one misfires. I replaced four ignition coils and spark plugs. Car sounds like it is missing a little and once in awhile it still loses power. No leaks and it is not overheating. A compression test was done on it and couple cylinders were not good. I was told head gasket was bad and to replace it. How does he know that is problem? why does it not act bad all the time? Could it be anything else?
