I've never done that test. I assume you've already verified FADEC throttle position sensors are 0% fully closed and the throttle idle speed screw is set 1-7/8 to 2 turns open. Maybe find a way to seal that up just for a ground run at idle... A nice blob of dough works surprisingly well with easy cleanup (flour + water, just don't twist the throttle). At least, it prevents you from replacing it and then finding out it didn't fix it.
