yea it was overtightened. just had to screw the bottom part back out. funny thing is my ignition coil went out also. thanx drft~

 

Sounds like the sparkplug was overtightened. This is a very common thing. Alot of people overtighten the plug, distorting it, or even fracturing it off, which sounds like what happened to you. I would go to who installed them ,if you trust them, have them extract it. Which is no east task! I would be pissed.
If you dont trust that person, shop. Have them pay for the service. Snap-on makes a really nice extractor set that works awsome. Dont try to remove yourself!

As some insurance, always use anti-seize on the treads of the plugs. Carbon can build up around the plug. Then when you try to remove it doesnt want to come out. Then you try harder only to snap it off. Anti seize lubricates the treads, preventing this from happening.
In the right hands this can be fixed in 20 mins.
