97 Chevy Cavalier need spark plug gap?

Well, all plugs have a gap and ussually they are somewhat close out of the box. Considering the year of your car you're prbably looking at.045-.060 gap.
Your local chevy dealer's parts or service dept. Should have no problem telling you if you tell them what motor you have. Should be able to take care of this without much problems, hope this helps.
