I know that my TB has some build-up of some whitish clear stuff in some of the ports (like the idle and ones that go to sensors) and I think it's causing a whistle. I think this because it has whistled when I had the old GSR intake manifold and it still makes the same whistle with the skunk2 (the whistle is at around 30-40% throttle at about 2-3.5k rpms). Anyway I was wondering what the best way to clean that build up out is. I dont want to damage any gaskets if there are any in particular that I might damage using seafoam or carb cleaner. What would you guys recommend?
