Aight, this is getting on my last nerve!!! I installed some brand new RC injectors a few months back. A month later I hear a vaccum leak. Saw fuel residue on the IM, the injector o-rings were fucked. The same orings that were only a month old !! After I pulled them out. It looked like pasta. So I replaced the O-rings with brand new from the dealership ones. And now I am still seeing a small residue of fuel on the intake manifold. No vaccum leak though. Could it be the injectors are leaking ? The orings still look to be in great shape. hmmmmm????
