Each time you start up your vehicle, the roar of the engine is a welcome sound since it means your car is in good health. The spark plugs play a crucial role in that easy start-up process. Trouble with these parts can create a domino effect on other operations and components of your car. Here are four warning signs that mean your spark plugs should be changed out before they cause further problems.

How to Tell It’s Time to Change Your Spark Plugs

1. Issues With the Engine Starting

Spark plugs take the electrical current from the ignition coils and use that current to spark the air and fuel combination within the combustion chamber. This process allows the engine to start up and continue to run as you drive. When the spark plugs aren’t properly relaying the electrical current, it can prevent your vehicle from turning on. 

2. Misfiring of the Engine

An engine misfire is another signal of problematic spark plugs. This happens when the engine runs but then stops for a short moment. The engine will then appear to go back to normal. It’s likely your spark plugs are having trouble using the electrical current to burn the air and fuel combination.

3. Trouble Accelerating

If you press on the accelerator and find your car doesn’t move as quickly or at all, it could point to a problem with the spark plugs. Your engine has to work harder as it doesn’t have the force needed to push the vehicle forward.

4. Increased Fuel Usage

In addition to playing an integral role in the engine start-up procedure, spark plugs also lessen the emissions released from your car. As they become damaged or old, they’re less efficient at minimizing emissions and providing a clean engine turnover. More frequent trips to a gas station might indicate they need to be replaced.
