Noisy throttle body??
When my engine is running and I have the air filter cover off (CFI) my throttle body (i'm guessing this is the thing that sticks out of the bottom of the tennis raquet air filter holder) makes a flicking sound. This is the only way I can describe it, it sounds very similar to a fly's/bee's wings when it's flying, only a little slower)
Is this normal in a CFI? If not, how much is it to replace the throttle body incl. labour?
