Well after a lot of reading I decided to change my plugs myself. Its an 04 with 94000 miles. 6 plugs broke and 5 of the 6 came out with the lisle. Unfortunately the rear plug on the passenger side isn't coming out. The tool threaded in nicely just like the rest but it pulled out without the end of the plug attached. Now it won't grip again since some of the metal got pulled out.

Does anyone have any suggestions or tips to remove it? Thx, Chris

 

You could get a bigger tap and allthread, helicoil the plug and try again, or pull the head
