Sounds like what happened to me when I tried out those Split Fire (Spit
Fire? Whatever...) plugs a few years back. They were new and supposed to
be great, but they lasted no more than 1500 miles before I had problems.
That was when I pulled my original platinum plugs off the shelf where I'd
stuck them (don't know why I didn't throw them out, but I'm glad I didn't)
and one by one put them back in, after hearing noticable improvement after
the first two went back in, I put the other two in and they ran fine. The
plugs had 90K on them at the time, and I ran them another 30k before
retiring them for good.
I'd still like to hear more about the Iridium plugs, and if there's any
benefit in our cars, built or otherwise.
