The old DIC in my 2000 9-3 was starting to throw codes so I was going to replace the DIC and spark plugs this last weekend. Three of the four plugs came out with no issue, but the last one was stuck tight (apparently the last time I had a mechanic replace them that one plug was over-torqued or not aligned correctly on the threads and then forced in). I could not loosen it with my torque wrench and an extension, so I then tried a long breaker bar to loosen it.
Lots of force on the breaker bar did not work....until suddenly it came loose....only to find out when I removed the socket that the top of the spark plug had broken off at the base and the base with the threads was still in the spark plug hole. I have never run into this before and am unsure now how to get that base of the last plug out without doing serious damage. Hoping the combined knowledge here can give me some tips.
