Hi guys.
After months of worry free driving the car started acting up. The idle started going up and down, and died eventually. Will not stay on idle or on unless I press on the throttle. Codes are:
ECM-130A Intake air leakage (No vacuum hose leaks were found)
ECM-4801 TWC (3way cat. conv.) Efficiency
ECM-262A Long term fuel trim
ECM-261A Long term fuel trim
At first it threw a code for MAS, which was replaced, codes were erased, car ran fine for a week, and issues came back. Codes remained the same except the MAS code. My guess now is a clogged breather box, I heard it can cause similar issues, I'm not sure if the codes would be the same though.
Previous work: New fuel pump+filter, New Air filter, spark plugs, motor mounts, oil change etc. All the maintenance stuff.

Breather box will not cause this issue.
Did you check all turbo air hoses for tears or loose connections at the turbo/intercooler? Give everything a good wiggle test, including the air hose from the mass airflow sensor to the turbo itself (sometimes the PTC nipple connector will degrade and cause a massive air leak there)
