When it comes to maintaining the health of your vehicle, there are few things more important than ensuring that your engine is running smoothly. One of the most critical components is the spark plug, which plays a vital role in igniting the fuel-air mixture that powers your engine. However, when oil gets into the spark plug, it can cause a range of problems, including rough idling. In this article, we’ll explore the relationship between oil in spark plugs, and how it can cause rough idling. We’ll also delve into the causes of oil in spark plugs, the symptoms of rough idling, and what you can do to prevent and fix the problem.
What is Rough Idling?
Rough idling refers to a situation where the vehicle’s engine is running unevenly, resulting in a jerky or stumbling motion. This can be accompanied by a range of symptoms, including:
- Difficulty starting the engine
