Symptoms

The most common symptom that you have a bad ignition coil is Acura check engine light coming on and engine misfire.

  • Check Engine Light On
  • Engine Shakes
  • Engine Misfiring
  • Rough Idle
  • Loss of power
  • The car will not start or dies at idle

What you will need

Procedure

  1. Park your ACURA on level ground. To avoid getting burned, allow the engine to cool down before you start replacing the ignition coils.
  2. Pull the hood release located under the dashboard (driver's side). Open the hood.  
  3. Disconnect the negative battery terminal. The cable you need to disconnect is the black cable with the (-) symbol next to it. The battery post that will be disconnected will either have the minus (-) symbol or the words NEG, NEGATIVE printed. The positive (RED) cable can remain connected.
  4. Remove the engine cover. In most ACURA the engine cover can be removed simply by pulling it up. If you see bolts on top of the engine cover remove them. remove acura engine cover to change ignition coil

While you can change just the defective coil, it is recommended to change all coils at once. If you are on a tight budget, you can replace only the bad coil but keep in mind that another coil may fail a few months down the road.
