2006 Cadillac DTS Question: How to remove the back spark plug which is stuck and will not come out.
you will have to excorsize little patience,and spray some WD-40 on threading. you will have to wait for it work its magic(a couple of hours). spray it on threading and take in a movie or something. now it still will not come out easy but it will come out. remember to coat threading on replacements with never seize prior to install. good luck. - arturo08
