Most people I spoke to had never heard of spark plug ceramics breaking. They all figured that I must have broke them either installing them or taking them out..... NOPE!

We'll see how mine look in a few weeks when I pull them out to look at them.

It sure is running good except for the vibration in the steering wheel when it idles. It has done this from about 60K on.

Everyone I talked to had never heard of this problem, with the exception of a few of you here. This problem is somehow related to the plug wires. I think it's the boots that went bad from me pulling them out to R&R the plugs the first time. I think I cracked them when I pulled them off the plugs, and somehow the spark is shorting out to the head through the middle of the plug instead of arcing across the gap. Therefore the broken insulators. But it's that part of it that I don't understand, it seems like there would be alot more resistance to go through the insulator and out to the head than to just continue on to the tip and across the gap. But I got the same questions from almost everyone, "are you sure you didn't break them yourself" ? "Did you drop them ? Did you overtighten them ? Did the plugs flop around inside the plug wrench" ?
