new iridium spark plugs
After I installed new iridium spark plugs, I noticed my car idles at about 700 rpms. Is that normal? cause it feels a bit low. Also, on a couple of occasions it has dipped even lower for a second and nearly caused my lancer to stall. Do I need to regap my plugs to a larger or smaller gap?

Yea I haven't noticed any performance difference either. They were a waste of money. My rpm's haven't dipped below normal since making this post, so I suppose if there ever was a problem, it fixed itself. From now on though, I'm definitly sticking with copper.

I tend to agree with TMHAMMER.... I just installed my (free - good thing wife works at autozone!) iridium ngk's today. I'm not experiencing any idle problems, although at initial startup I noticed the car idled silently - nice. I haven't driven too much yet, but after my first drive idle seems normal (not silent however). I think there was a teeeny bit of performance gain. I was also thinking I had some smoother shifts and slightly better acceleration.
