Engine misfire is a rather common issue that can occur in vehicles, both old and new, and it can have a negative impact on their overall performance and reliability. Essentially, it refers to the failure of one or more cylinders to ignite fuel properly, which disrupts the combustion process. This phenomenon can be caused by various factors, including problems with the ignition system, fuel delivery, or cylinder compression. What exactly is an engine misfire? An engine misfire occurs when one or more cylinders fail to ignite properly. It's an instance where the engine doesn't behave cooperatively and causes disruptive effects. Engine misfires happen when one of the cylinders does not produce sufficient spark or compression and lack of fuel. It could involve more than one cylinder. It can be caused by a faulty spark plug, fuel injector, ignition coil and or worn cylinder. Why do engine misfires happen? There are a variety of factors th ... read more
