Hey guys, intermittent problem here. It seems that some times my car definitely isn't running on all 6 cylinders, as there's a noticeable lack in power. It's not all the time though, as it often goes from a loss in power to being back to normal. A couple days ago, and this has only happened once, it was backfiring for a bit too. Below 3000rpm it would run like s***, then be a bit better past that but still with no power. Any suggestions on what could be the issue? I've heard that in rare cases changing the spark plugs could fix it, but I doubt that's the only issue.

I have the same sort of issue. Sometimes my z just wont get up and go as it should. I have read a couple of forum entries and havent really found any straight answers. I just replaced my spark plugs so I dont think that is the issue, did you figure out your problem? Got any ideas?

stock NGK's and .44 gap make a world of difference. They are more expensive but worth it

Even on a NA? I thought I heard somewhere that the necessary plugs and gaps are different for the NA's

Video says otherwise, I believe Jared is right. Spend around 50 bucks to see if its the problem, if not atleast my z will have proper plugs
