I have had my RX-8 for a year now, and since i got it, it has had a small problem keeping a steady idle when in park, or in gear when i am stopped. And at times its a little sluggish to start. It runs strong and problem free when im driving it. does anyone know if that could possibly be the ignition coils?

 

Please give us the history on your car, year MT/AT,miles etc just anything you can add... The service it's had parts replaced.
