Can a bad coil cause the engine to miss?

Yes, a bad coil can cause the engine to miss. A coil is responsible for converting the battery's low-voltage power into high-voltage power that is used to create a spark in the spark plug. If the coil is not functioning properly, it will not be able to provide the spark plug with enough power to create a spark, which will cause the engine to miss.

There are a few signs that can indicate that you have a bad coil, including:

- The engine is running rough or jerking

- The engine is misfiring

- The engine is hard to start

- The check engine light is on

If you are experiencing any of these symptoms, it is important to have your vehicle inspected by a qualified mechanic to determine if the coil is bad and needs to be replaced.
