while doing a look over of my 04 lade esv I discovered a busted exhaust stud on the drivers side right at of all places the rear at number 7 spark plug.I need someones possiable suggestion on how to get the remainder of the bolt out without removing the heads.its currently flush with the head,:want:I did a overlook after hearing some detonation after shifting into gears on lite throttle and heavy throttle and yes i do use 91 premium fuel.do you guys figure this leak would contribute to my problem as its unmetered air before the o2 sensors,thanks for all can help

I just don't think you have the room to use something like an easy out to get the old bolt out without removing the head because there is not enough room, but maybe one of our GM techs will chime in.
