I've seen a few posts relating to this recently, but the information is not quite "hitting the nail on the head" for me.
First off, I'm experiencing a "missing" problem and have been for quite some time now. I've tried a number of different fixes (Just ask my wife! LOL) but all provide very little if any improvement. I'm now suspecting that my plugs are gapped incorrectly and or inconsitantly. I made the mistake of not gapping the plugs when I installed them. That's my bad, but now I need to fix it. It is also worth noting that I replaced my plugs (I purchased them from the dealership...not sure if they are the douple P or not since they have replaced our plugs with a different one) less than 13,000 miles ago. So, in my opinion, they should still be good.
That said, I've got a '95 supercharger with an '89 pulley on my '89 SC. The usual, air silence removal, etc. I'm still running the stock exhaust set up for now, so I haven't done more on the intake yet. This always happens at or near WOT. However, it does not always happen when I'm accelerating hard. Sometimes it is a seemingly regular miss under acceleration. I'm suspecting my #3 cylinder as I have an exhaust leak at the header there and the sound (ticking) becomes less regular when I feel the miss. Other times the engine completely cuts out and comes back on. To me it is obvious that it is an ignition issue. Whether it is the plugs or not has not yet been determined. (That's what I'm trying to do) I do not hear any pinging as would be associated with detonation and I don't think that I have enough mods to be too concerned with detonation at this point. I simply think that for what ever reason, I'm not always getting spark. After reading an article on the iridium plugs (under another post) I thought that maybe my smaller pulley could be contributing to that problem. Especially since my dumb @$$ didn't gap the plugs to begin with.
Now to my question: Would it be worth it to simply remove my plugs (assuming they are good) regap them to the proper gap and reistall them or simply get new plugs? Either way, what would be the recommended gap that I should run. I'm pushing 14 to 14.5 lbs of boost at WOT, if that helps. Please let me know so I can get this done and make my baby run good! Thanks.
