Your vehicle’s ignition coils play a crucial role in its performance. They convert the battery’s voltage into the high-voltage charge necessary to create a spark in the spark plugs, which ignites the fuel-air mixture in your engine. However, ignition coils wear out over time, leading to performance issues and potentially leaving you stranded if not addressed. So, how can you tell if your ignition coil is failing? Let’s explore some warning signs and their implications for your vehicle. Misfiring or Rough Engine Performance One of the most noticeable signs of a failing ignition coil is engine misfiring. You might feel your car hesitate, jerk, or sputter, especially when accelerating. This happens because the ignition coil is not supplying enough voltage to the spark plugs, causing an inconsistent combustion process. Left unchecked, misfiring can lead to increased emissions, decreased fuel efficiency, and even damage to other engine components like th ... read more
