Spark plugs have an essential purpose by providing the necessary spark to enable the combustion process. Without the spark plugs, your car's engine cannot transform the fuel into usable mechanical energy. Not only is it a vital piece, but they are constantly in use while you drive. Specifically, spark plugs fire at a rate of about 1,500 per minute of driving. If any sparks are old or failing, you'll often encounter a glitch or stumble in the engine's output. With such an important task, you should replace worn-out spark plugs as soon as you notice the symptoms of wear. Other than a sputtering engine, what other signs indicate you need a spark plug replacement?
Signs That Your Spark Plugs Need a Replacement
- Troubles starting engine
- Knocking sounds
- Engine misfires
- Rough idling
- Lowered fuel economy
- Difficulty accelerating
It's critical to replace spark plugs as soon as they are old or worn out. If you neglect to do so, you can cause severe damage to other parts of the engine. In some situations, it is possible to determine if there are other engine problems based on the condition of a spark plug. For instance, if a spark plug looks damp, it could indicate engine flooding. On the other hand, if a spark plug is black and oily, it could mean you have an oil leak, possibly from a leaky gasket.
An inspection of spark plugs at home does not always provide an accurate assessment of your vehicle's shape. It is highly recommended that you take your car to an auto professional and have it pass through a multi-point inspection to ensure your vehicle is okay to run.
How Often Should Spark Plugs Be Replaced?
The best source to find information pertaining to your vehicle's spark plugs is your trusty (and probably dusty) owner's manual.
