Edge problem after plug change

My first question is why was spark plug for number 6 breaking? That is a little odd in itself.
Remove and check all the plugs again. It is a good starting point since you now have no codes.

The edge stores your stock tune and uploads its own custom written (canned) tune that edge loads onto their programers from their factory.. Its possible the "update" your mechanic did to PCM calibration is whats causing an issue with the edge.. You may want to try updating the edge.. If its a CS or CTS then definitely update it..
Also.... check the battery terminals for a good, clean and tight connection.
Check the cop connectors on each cop, and seriously consider pulling every plug, and replacing them. (For the sp515.. Use the appropriate amount of anti-seize lubricant, and dielectric grease this time around..

We don't really know, but the best we could figure out was that maybe it wasn't all the way seated into the cylinder. All the plugs broke coming out, but on this one, the porcelain really got crushed into many little pieces and after trying to blow them out with air (with no success), we just turned the motor over to blow them out. When putting the new plugs back in, all of them but this one could be threaded down without a ratchet until it hit the bottom and then snugged up, but this one required a ratchet just to get it down. It was tighter for some reason going down (basically it felt different than all the others). Because it was harder to thread down, we just thought that maybe it wasn't seated properly and wasn't making a good seal in the cylinder. After a new plug and muscling it a bit, it stopped misfiring when he was using his scanner to watch it run. But yes, I don't see how having a broken plug with no electrode and the porcelain was almost touching the bottom of the metal sleeve didn't throw a misfire code.

Well I pulled plugs 5 and 6 to inspect them tonight. Plug 5 was ok other than having the small chip/crack on the metal sleeve from where it was in 6 briefly.
Plug 6 on the other hand was a different story. The top of the plug was covered in anti seize and gas, and the gas had made its way all the way up the inside if the boot and was on the coil. Here are the pics...

What could be causing the gas to get up to the coil? Too much A/S? Threads damaged in the cylinder? Something else?
