    Bad plug?

    Hey guys took my spark out today, at first ran like a champ then I stoped and ideld for a while after that it started running at max 35 to 40 mph rpm staying around 6500 and occasinaly try to pick up and go. it did that most of the drive a few times it picked back up and ran full rpm and mph but if I stopped and idled for more than a few min it would start again. Does that sound like a plug going bad?

    So is there a plug that autozone carries that will work in the spark? Or is there any warranty that covers premature plug failure?

    How do you check the plugs without taking off the whole top?
