Hi Virginia. Thanks for contacting us today. It’s always best to first correctly diagnose the source of the misfire before replacing any components. It is possible that the coil pack is faulty, in which it is best practices to replace them all at the same time. But, it could also be a faulty firing fuel injector. You might want to have a professional mechanic come to your location to complete a misfire inspection, so they can determine exactly what needs replacement.
