Hi Lewis. Thanks for contacting us today. Oil can impact many electrical system components, especially if the oil leaks into the spark plug well. It’s probably best to have a professional mechanic complete an engine misfiring inspection so they can isolate the root issue and ensure the right repairs can be completed.
