Hey guys i have been trying to track down this issue but cant a link to any solutions. I have the stillen kit and at first had a legit faulty Throttle body so i replaced that and car was running great. Then suddenly one day it went into limp mode, i used the uprev cable and it have me the same code, same bank, p1239, bank 2. Is it the harness? I have read some guys think the harness it comes with isnt good but this on going now and the car even cmears itself of the code and will drive fine then randomly go into limp mode and throw that code. Please help, this is a real pain in the butt.
