What does a car sound like when spark plugs are bad?

If your car is making a clicking sound, it may have bad spark plugs. Spark plugs create a spark that ignites the fuel and air in the engine. When they are bad, they may not be able to create a spark or the spark may not be strong enough to ignite the fuel. This can cause the car to run rough, make a clicking sound, or even stall.

You can usually tell if your spark plugs are bad by checking the plugs themselves. The plugs will be blackened if they are not working properly. You can also check the engine light. If the light is on, it may mean that the spark plugs are bad.
