Alright, the idle adjustment didn't change the problem same clunking at idle, I set the butterfly slightly open with the screw and did a voltage check on the TPS. No dice. I'm going to take the IAC off and check for movement, after that I can only assume EGR or bad injectors.
One strange thing it does is, when the gas is touched the RPMs jump about a 1k and stay there for a few before it drops back down to a death chug.
No codes until the engine dies.
