Re: [MBZ] The miss is fixed!
Donald, I don't think it was the torque value. It is due to the hard foam piece that holds the top end of the plug in the socket to keep it from falling out. If you pull on the wrench handle and don't keep the socket or extension straight in relation to the plug, with some down force at the wrench head as you pull up on the handle, then the foam will transfer the pressure to the insulator and break it.

I guess I torqued them a little too hard. The ceramic insulation was cracked (badly on one and barely on the other). I replaced the plugs and went for a drive and it ran fine - no miss! Donald H.

That is a good point. When I put the new ones on, I made sure to pull the wrench off straight. Donald H.

Re: [MBZ] The miss is fixed!
That would also be good but I was talking about when you are pulling on the handle of the wrench to turn it. As it tightens and you have to pull harder you must also at the same time apply opposite pressure at the head of the wrench to keep the extension and the plug socket straight. Otherwise pulling on the handle hard tends to pull the extension out of line and when you pull real hard the force is transfered to the insulator and snaps it off sideways. Try putting the extension and socket on a bolt that is easily accessible and pull on the handle and see how the extension gets pulled out of line. You can even pull the whole socket off the bolt or nut sideways when pulling real hard.
