wastegate actuator rod is rattling

I dont know what its hitting, but not under load its constant at 2k *which is irrelevant*

we took a wrench extension and put even so slight leverage when the engine is at 2k and it stopped it completely. I do not know what the rod is vibrating on. anyone else have this problem

t28 specR turbo if that helps

Sounds like it might be open and causing a vacume leak which would explain the 2000rpm idle ????
