When to replace your spark plugs
Keeping up with your vehicle’s maintenance is a lot harder than it sounds. Sure, you probably know when to get the oil changed and when the tires need to be filled with air, but there are so many components in your vehicle that need regular maintenance and upkeep. Spark plugs are an important contributor but are often forgotten about by the average driver. Read on to learn when you should replace your spark plugs!
What do spark plugs do?
Spark plugs, as the name suggests, are what provide the initial spark that causes the combustion within the engine to start the vehicle and keep it moving. A healthy set of spark plugs are essential to keep the engine working properly, but over time, unburnt gas and oil can lead to a buildup of debris and residue that will make it tougher to start your vehicle. When this happens, it’s time to replace them. Generally speaking, spark plugs will usually last for 100,000 to 120,000 miles.
Signs that the spark plugs need to be replaced
You can wait it out until your vehicle reaches the 100,000 to 120,000 mile mark with the same set of spark plugs, but not all spark plugs will last that long. It’s better to get them replaced when you start to pick up on the warning signs than to wait it out and be stuck with costly engine damage down the road. Some of the signs that indicate it’s time for new spark plugs include:
- Rough engine idling
- Difficulty starting the vehicle after it has been off for a few hours
- Engine misfiring
- Engine surge or hesitation
- Poor fuel efficiency
- Poor acceleration
