The spark plug is a vital component in a car’s electrical system. To keep excellent fuel efficiency and power in your vehicle’s engine, your spark plugs should always be in a good condition. Below are symptoms of failing spark plugs:
- Your vehicle engine is hard to start, especially on cold mornings.
- You receive a slow response when you step on the gas pedal, ideally your car does not accelerate as quickly as it should.
- You might observe a decrease in gas mileage. This implies that you need to gas up more often than before.
- Your engine now runs rough, this means the motor is not running smoothly on all cylinders and fuel ignition is not efficient in one of the cylinders.
- You observe engine combustion problems. Often, failing spark plugs cause the flow of electrical current to get erratic and uneven. Sometimes, the electric current flow is normal and sometimes the flow is abnormal.
To prevent spark plug failures in the future, you should change it before it wears out. Ideally, you should change spark plugs every two years if you own cars that make use of electronic points. If you own older models that have contact breaker points, spark plugs should be changed every year.
