Re: efi de-carbing

You don't have a carb but you do have a throttle body which for purposes of decarbing would work. I don't see why you can't remove the airbox and pour the decarb solution into the throat of the throttle body (which looks a bit like a carb it just meters air not fuel). The EFI fuel injectors will do what they do while you pour it in. If I'm wrong somebody will says so.
