Most people don’t think twice when it comes to spark plugs; some don’t even know what they are and what they do. They might be small, but they are very mighty and are a crucial part of keeping your car running. Here are the tops signs that your current spark plugs are failing:
Your Engine Fails to Start
Your spark plugs have a critical function in your vehicle: to provide the spark that powers the engine! Old, worn-out spark plugs have a more challenging time creating the spark that actually powers your motor. If your car stalls when you are trying to turn it on, there could be a problem with spark plugs or damaged spark plug wires.
You’re Getting Gas More Often
If you notice that you aren’t pushing the exact miles per gallon (MPG) and stopping for gas more frequently, then it might be time to look at your spark plugs. Spark plugs that are worn down can increase your fuel consumption because they aren’t effectively burning the fuel that goes to your engine. Did you know that a misfiring spark plug can reduce fuel efficiency by as much as 30%?
Your Car is Making Noise
If your engine is making a rattling or knocking sound, your spark plugs might be the culprit. If you’re unsure, then it is best to take your vehicle into our shop so that you can get a proper diagnosis.
Your Car Won’t Accelerate As Fast
Most people are familiar with how their vehicle handles and drives. If you are brought to attention that your car isn’t as responsive, especially when you hit the gas pedal to accelerate, this could be traced back to your spark plugs.
Your Check Engine Light Comes On
Most failing spark plugs will trigger your check engine light to come on or even flash. When this light comes on, it is most likely related to misfires with the engine. However, it is important to mention that a check engine light could be potentially caused by other things, not just a spark plug problem. This unclarity is why we recommend getting your car checked by a trained technician at Olympic Transmissions & Auto Car to locate and trace the actual problem accurately.
Continuing to drive with worn-out or damaged spark plugs can ultimately cause engine damage, so don’t put it off. Please make an appointment at Olympic Transmissions & Auto Care, so our expert technicians can examine your vehicle’s health.
