Hi, i cant find one but i would need to remove to thoroughly check this,Would it not affect the engine when it was warm if this was the case as it runs perfect when warm ?

Found the problem by holding the "plate" and using a finger on the butterfly, found I could move it. Needless to say the throtttle body has to be off the manifold to find this all out !!

Hi and thanks will get this checked out and let you know.
