Oil in a spark plug hole will generally cause a misfire to occur. This can happen when the spark plug tube seals get oil in them from not sealing correctly. This will often cause misfires resulting in the Check Engine Light also coming on. The misfire, when persistent enough, can cause a lack of power which may cause the car to stall as well. As you may know, however, a misfire can happen for many other reasons as well, such as poor fuel pressure, dirty or leaking injectors, a faulty O2 sensor, and many other things. The Check Engine Light should indicate one or more codes which will point to potential problems.
