What is an ignition coil replacement?

The ignition coil is an important part of your ignition system, transforming voltage into high voltage pulses to help fire the spark plugs. A malfunctioning coil needs to be replaced so that the vehicle can start safely. Here are the basic steps for an ignition coil replacement:
  1. Check ignition to ensure it is in the “Off” position.
  2. Disconnect or remove the coil.
  3. Install replacement coil and reattach any electrical connections.
  4. Adjust timing as needed.
  5. Road test to ensure proper functioning.

You may need an ignition coil replacement if your vehicle is struggling to start or accelerate. This service is fairly straightforward, but it does require special skills. Mechanics may need:

This service is very important. It is safe to drive with a malfunctioning ignition coil. However, you will experience poor fuel efficiency and weak acceleration. Misfiring can be dangerous, as it allows unburned fuel to enter and damage the catalytic converter. Eventually, your vehicle may fail to start at all—and then you’d be stuck wherever you parked.
