These cars are VERY particular when it comes to plugs & wires. You can run a search in the troubleshooting & duratec maintenance sections for words like "bucking" & you'll come up with all sorts of horror stories.
The Zetec is less prone, but kennards situation stood out because it was sooooo extreme. Actually missing so bad he was shattering plug insulators. That is one mean misfire.
A good set of Autolite plugs & Autolite or new stock wires should do the trick just fine.
Well, you shouldn't oughta assume it's necessarily the wires and plugs, especially if they're new, if you haven't checked other possible sources of misfirage like a clogged EGR, or the 98+ equivalent, a stuck VCT.

Originally posted by AliasJerk:Today we were taking out the Champion Double Platinums and my dad was working on unscrewing the 2nd cylender Plug, and he goes to push on it then it just goes freely. He picks up the socket wrench to find about a quarter of the spark plug on the end of it. So that was the problem all along, I had a cracked Spark plug.
