thiscan be a few things. Alot of people mistake oil on the plugs for what is actually gas on a misfired plug. But the best thingto do is check the cylinder that had the oil for compression. that can tell alot as it could be valve seals,rings etc. For your idle problem, tryusing choke cleaner and clean the throttle plate wth your engine off. Tha causes a lot of idle problem. It will be hard to start after cleaning. Make sure to clean both sides..
