I have a 95 CV w/ 108K miles.I was changing the plugs and found that #1 and #8 plugs were apparently rounded off by a previous owner! I cannot get them out. Any ideas about removing plugs that have been rounded off? (Also, this may mean that the plugs are in so tight they may not come out)[:@]

 

Usea socket that is just a little smaller, and install extenxion and use hammer to tap socket over the plug. Be careful not to damage the porcelin part of the plug. Either that or break it off and drill it out(which you DO NOT want to do)
