    Throttle Body

    looked at my throttle body today and its black! how does that make sense when its purpose is to let through air from the inlet when you accelerate? And its somewhat no where near the combustion chamber and near the air outlet?

    Thanks in advance.

    The crankcase fumes are vented via the throttle body so they are burnt in the engine. So oil residue gathers in the throttle body and particles stick to it. From time to time it pays to give the throttle body a quick spray with carb cleaner.
