Trying to track down a vacuum leak on my supercharged ls3. I just installed FIC1000 injectors purchased from a member on the CF. I have had an idle issue since the change. Checked all vacuum lines and can not find the leak. The original injectors pulled had RED o rings were they seat in the intake manifold. The FIC injectors have a green o ring were they seat in the intake manifold. Could the green o rings be to small? There are no fuel leaks were they seat.
Thanks, Michael

Thanks for all the advice. I really apriciate it. The red o rings fixed the vacuum leak. Form the pics you can not tell a big differance in size but there is. Amazing how you overlook the easy fixes when in your head your thinking it is something major.
