Spark plugs are an essential part of your vehicle’s engine, and they need to be replaced regularly. But what do you do if you have a bad spark plug?

Spark plugs are responsible for igniting the gas mixture in your engine, which produces the power that drives your car. They are located in each cylinder of your engine, where they create sparks by sending an electric charge through a gap between the center electrode and ground electrode. The spark ignites the air-fuel mixture in that cylinder and sends it out through the exhaust pipe.

You might experience problems with your vehicle’s spark plugs if they are old or have been damaged by debris in the engine. This can affect performance and reduce fuel efficiency because there is less fuel being burned in each combustion cycle.

How long can you drive with bad spark plugs?

If your spark plugs are worn down or damaged, then there is no set amount of time that you can continue driving with them before experiencing problems with performance or fuel efficiency. The best way to determine whether or not it’s safe to continue driving is by checking for misfires on a regular basis (every 2,000 miles). If you notice misfire symptoms such as rough idle, stalling or hesitation during acceleration, then it’s probably time to get.
