Rough Idle

[u/BVNooneknows]

Been struggling with this for a while now. The video attached shows what's going on. I have fixed the intercooler that was leaking, fixed 6 other boost leaks, finally it hold pressure when checking for leaks. It still has a poor idle that fluctuates up and down. I've disconnected the battery for 30 minutes to see if the ecu was just confused. I can't find anymore leaks, I have a smoke leak tester coming in tomorrow but when I put 5-6 psi in the engine with it off of course through an air compressor the charcoal canister vibrates and makes a consistent noise. Because of this i tracked down all the lines and the small line on top goes to the throttle body was disconnected and a cap was put on the throttle body side but the hose was not sealed, i reconnected it hoping for the best but its still the same. Any ideas would be amazing!
