  1. Park your Forester.
  2. Pop the hood.
  3. Disconnect the battery.
  4. Remove the engine cover, if applicable.
  5. The ignition coil is on top of the engine, in the middle. There are four spark plug wires connected to it. With a white marker, write a number on each spark plug wire. It’s important that the spark plug wires go back in the right places after you install the new ignition coil.
  6. Disconnect all the spark plug wires from the ignition coil.
  7. There are either 2 or 3 bolts securing the ignition coil in place. Remove all of them.
  8. Remove the ignition coil.
  9. Put the new ignition coil in. Secure it in place with the 2 or 3 bolts you just removed.
  10. Connect all the spark plug wires according to the numbers you marked on them.
  11. Place the engine cover back on the engine, if applicable.
  12. Connect the battery.
  13. Start your Forester and then see if any of the previous symptoms persist. (You can see a list of the symptoms of a bad ignition coil here.)
