Its been a long time since anyone posted here but I am having the same issue with my stillen kit on my 350Z. I saw that some folks have replaced the extension harness' and the issue went away. I just ordered them today in hopes to fix this issue. Brutusvk, did you ever get you P1239 code to completely go away?
