I've been doing so many vacuum leak tests my mind is going to explode! Every now and then a hissing sound will pop up in and around the fuel rails. I don't notice a fuel leak with the smell of fuel, but when I do the vacuum test with water around the base of my injectors there is a noticeable sign of air bubbles blowing at the bottom of the injector o-ring. Is this a big enough leak to throw off idle and stalling out the car at start?
