Spark plugs play a crucial role in the combustion process of your car’s engine. They are responsible for igniting the fuel-air mixture in each cylinder of the engine, which creates the power that propels your car forward. Without properly functioning spark plugs, your engine may misfire, have reduced power, or even fail to start altogether.
The basic function of a spark plug is to create a spark that ignites the fuel in the combustion chamber. The fuel mixture in the cylinder is compressed by the piston, and when it reaches the spark plug, a high-voltage electrical current jumps the gap between the center electrode and the ground electrode, creating a spark that ignites the fuel. This explosion pushes the piston down, which ultimately powers the wheels of your car.
There are several factors that can impact the performance of your spark plugs, including age, wear and tear, and exposure to contaminants. Regular maintenance and replacement of your spark plugs can help ensure that your engine is running at peak performance, maximizing fuel efficiency and minimizing the risk of engine damage. Understanding the role of spark plugs in your car’s engine is crucial for maintaining your vehicle’s overall health and performance.
If a spark plug is worn, dirty, or damaged, it may not create a strong enough spark to ignite the fuel mixture in the cylinder. This can cause a misfire, where the fuel in the cylinder doesn’t ignite at the right time or doesn’t ignite at all.
Misfires can lead to a range of engine performance issues, including reduced power, rough idling, hesitation or stumbling when accelerating, and decreased fuel economy. Over time, misfires can also cause damage to other engine components, such as the catalytic converter, which can be expensive to replace.
In addition to misfires, faulty spark plugs can also lead to incomplete combustion of the fuel mixture. This can cause excess fuel to be dumped into the exhaust system, which can lead to increased emissions and reduced fuel economy. Over time, incomplete combustion can also lead to the build-up of carbon deposits on the spark plugs, which can make the problem worse.
Overall, the impact of faulty spark plugs on engine performance can be significant. Regular inspection and replacement of spark plugs can help ensure that your engine is running at peak performance, maximizing fuel efficiency and minimizing the risk of engine damage.

Factors that can impact How long you can continue driving with faulty spark plugs
The amount of time that you can continue driving with bad spark plugs can vary depending on several factors. The severity of the spark plug’s condition and the age of your vehicle are two key factors that can impact how long you can continue driving.
| Factor | Impact |
| Severity of condition | If the spark plug is only slightly worn, you may be able to drive for a short period of time before experiencing issues. However, if the spark plug is severely worn or damaged, you may need to replace it immediately. |
| Age of vehicle | Newer vehicles with more advanced engine management systems may be able to compensate for faulty spark plugs for a longer period of time than older vehicles with less advanced systems. |
| Driving conditions | If you do a lot of stop-and-go driving, such as in heavy traffic, faulty spark plugs may cause more immediate issues than if you primarily drive on highways at a consistent speed. |
| Maintenance history | Regular maintenance, including regular spark plug replacement, can help prolong the life of your engine and reduce the risk of immediate issues from faulty spark plugs. |
How long can you drive with bad spark plugs ?
Driving with bad spark plugs can have a negative impact on your vehicle’s performance and fuel efficiency. If your spark plugs are not functioning properly, they may not be able to ignite the fuel in your engine properly, which can lead to issues such as misfires, reduced power, and poor fuel economy.
The length of time you can drive with bad spark plugs depends on the severity of the issue. In some cases, your vehicle may be able to continue running with bad spark plugs, but you may experience poor performance and fuel efficiency.
As for mileage, it’s difficult to give an exact number since the lifespan of spark plugs can vary depending on factors such as the make and model of your vehicle, driving conditions, and maintenance history.
Generally, spark plugs should be replaced every 10,000 to 100,000 miles, depending on the type of spark plugs used and the manufacturer’s recommendations. However, if you are experiencing issues with your vehicle’s performance, it’s best to have your spark plugs inspected and replaced if necessary, regardless of the mileage.
Types of Spark Plugs and their Life Span
It’s important to note that the lifespan of a spark plug can vary depending on several factors, such as driving conditions, engine type, and overall maintenance of the vehicle. Regular maintenance, including routine inspection and replacement of spark plugs, can help ensure optimal engine performance and prevent damage to other engine components.
| Types of Spark Plugs | Life’s Span |
| Copper Spark Plugs | 20,000 miles |
| Iridium Spark Plugs | 40,000 – 60,000 miles |
| Platinum Spark Plugs | 60,000 – 100,000 miles |
| Double Platinum Spark Plugs | 100,000 miles or more |
| Ruthenium Spark Plugs | 60,000 – 80,000 miles |
| Nickel Spark Plugs | 30,000 – 50,000 miles |
| Silver Spark Plugs | 20,000 – 30,000 miles |
Can you still drive your car with bad spark plugs?
Driving with bad spark plugs is not recommended and can have a significant impact on your car’s performance. Faulty spark plugs can cause a variety of issues, including misfiring, reduced power, decreased fuel efficiency, and even engine damage.
In the short term, you may be able to continue driving with bad spark plugs, but this can cause further damage to your engine and lead to more expensive repairs down the road. Additionally, your car may become less reliable and less responsive, making it more difficult to drive safely.
If you suspect that your spark plugs are bad, it’s best to have them inspected and replaced by a qualified mechanic as soon as possible. Regular maintenance, including routine inspection and replacement of spark plugs, can help ensure optimal engine performance and prevent damage to other engine components.
Ultimately, driving with bad spark plugs is not a sustainable or safe solution, and it’s important to prioritize the maintenance and upkeep of your vehicle to avoid further damage and keep you and your passengers safe on the road.
Which condition to see to replace the spark plug ?
There are several conditions to look out for when determining if your spark plugs need to be replaced. Here are some key signs that it may be time for a spark plug replacement:
Mileage: As mentioned earlier, a general rule of thumb is to replace spark plugs every 13,000 to 50,000 miles.
Difficulty starting the engine: If your car is having trouble starting, this may be a sign that your spark plugs are worn out and need to be replaced.
Rough idling: If your car is idling roughly, this may also indicate that your spark plugs are worn out and not firing properly.
Reduced power: If your car is not performing as well as it used to, it may be due to worn out spark plugs.
Decreased fuel efficiency: Bad spark plugs can cause your car to burn more fuel than necessary, leading to decreased fuel efficiency.
Check engine light: If your check engine light comes on, it’s always a good idea to have your spark plugs inspected, as this can often be a sign of a faulty spark plug.
By keeping an eye out for these conditions and performing regular maintenance, including routine inspection and replacement of spark plugs, you can help ensure optimal engine performance and prevent damage to other engine components.
Can Bad Spark Plugs Stop A Car While Running?
Yes, bad spark plugs can cause a car to stop running while it’s in use. When spark plugs are faulty, they may not provide the necessary spark to ignite the fuel in the engine, causing the engine to stall or shut off completely. In addition, worn out or damaged spark plugs can cause misfires and other issues that can impact the engine’s performance and potentially cause it to stop running.
If your car has a gasoline engine, bad spark plugs can definitely cause it to stop running while in use. Gasoline engines rely on a spark from the spark plugs to ignite the fuel and air mixture in the combustion chamber, and without a proper spark, the engine can stall or shut off completely. In addition, bad spark plugs can cause misfires and other issues that can impact the engine’s performance, leading to potential issues like stalling or engine failure.
However, Regular maintenance, including checking and replacing spark plugs as needed, can help prevent these issues and ensure your engine continues running smoothly.
