Well I finally did it.I used a one quarter 1/4 reversible drill bit drill just a r.c.h. past a 1/4in. followed by a #4 spirial easy out extractor.extracted by hand.Installed replacement,fired her up and she purrrs like a kitten.NO Black carbon NO stalling Who would think a broke CTS would screw up fuel delivery and all that time,not one dang code.Now if I could just get my monitors to complete their cycles I could smog it and drive it!
