Spark plugs are responsible for creating the spark that ignites the fuel in your car's engine. If the spark plugs are not working properly, the fuel will not ignite and the engine will not run. This can cause the car to stall.
There are a few different things that can cause spark plugs to go bad. One common problem is that the spark plugs can become fouled with carbon deposits. This can happen over time, especially if you drive in dusty or dirty conditions. Another common problem is that the spark plugs can become worn out. This can happen over time, especially if you drive a lot.
If you think that your spark plugs may be bad, you should take your car to a mechanic. They will be able to diagnose the problem and replace the spark plugs if necessary.
