Hi if the throttle body is faulty it wont move the butterfly in the unit to the start position [slightly open] when hot it may well work better as all the tar like substance is softer and allows movement try removing the throttle body and cleaning it, if that wont work you will need a new unit as they are also prone to stripping teeth off the plastic gear wheels in the control unit.

Hi much as I hate to point this out if the throttle body has gone that will give you all sorts of problems starting and when it gets running it is probably running a default strategy which means yes it runs and moves but what you have is a get me home facility, surely common sense would dictate that would be changed first as if its not working properly that would throw up injector and air faults as the engine has no real control over either of the previous mentioned items, nearly all diesels use Total Throttle Position as the datum for air intake and injection.
