Warning Signs to Change Your Spark Plug

If your car isn’t starting the way that it should be, one problem could be your spark plugs. Spark plugs create an electrical spark inside of internal combustion engines, which ignites the compressed fuels and get the engine moving. If spark plugs are old or not all of them are working, this can create rough starts or make it impossible to fire the engine at all.

Most spark plugs should be replaced every 30,000 to 45,000 miles. However, the more expensive platinum spark plugs can last up to 100,000 miles before they need to be replaced. A rough start is a sure sign of old spark plugs but there are other signs. A lack of a spark can create poor fuel efficiency or cause your car to vibrate or even stall while idling or accelerating.

Finding out if your spark plugs need to be changed is easy. Any mechanic can quickly hook your plugs up to an oscilloscope to check their secondary ignition pattern. Worn spark plugs will cause a sudden spike in voltage that is simple to detect. Replacing spark plugs is cheap, easy and can have a major impact on the quality of your ride.
