If a Spark Plug is Bad, What Happens?

Spark plugs are small, simple devices that ensure that your engine can perform at its peak. When working well, your spark plugs are the primary point for engine combustion. How does this work? The ignition coil sends high-voltage electricity to the spark plug, which ignites to activate the engine cylinders. This powers the engine so that you can get back to cruising around Streamwood. As you might have guessed, if a spark plug is bad, it can create huge problems: engine misfiring, rough idling, and even failure to start! Thus, it’s definitely worth it to pay attention to your vehicle spark plugs as you’re conducting your routine vehicle maintenance.
