Is your vehicle misfiring, having a rough idle, dying at idle, or is the engine shaking? Learn how to fix it by simply replacing the Ignition Coil.

Changing the ignition coil on Acura vehicles is not as difficult as you think. The four-cylinder Acura engine is very easy to work on, and you can change the ignition coils yourself in less than an hour.  The 3.5L V6 Acura engine requires slightly more time.
