Answer
Hi Daniel:

Well first off if the car has less then 36000 miles it should be a warranty repair. do you know what cylinder(s) are misfiring? if you changed all thhose parts on the ignition system and it's still misfiring then it's either a mechanical issue with the engine or a fule delivery issue like a fuel injector. Good luck :)
