hi there all Audi lovers I’m having an idling issue no check engine lights or anything. When engine gets warmed up it starts. Going from rolling to stop sign or red light and engage clutch she wants to quit. I have to feather gas to keep it alive. I replaced a basin line going to occ valve, and 90degree suction hose fitting as well as cleaned throttle body and replaced intake manifold gasket. I have no idea where to start now. HELP!!!!please
