So many variables in one message... Did you take intake manifold itself off (you mention O rings -- seals around ports on heads?). Is tricker to reinstall with air tight fit than I first realized. While car idling, spray carb cleaner around each port at head mating surface to see if any have vacuum leaks. Also spray each fuel injector port (you don't mention replacing the "top hats"). If removed, recheck the cold start tube (access between cylinders #1 and #2). Somehow ensure idle speed motor takeoff is air tight (suggestions anyone? I just stuck a big vacuum cap on mine and threw away). And spray the U pipes while you're at it. Then variable #2...
