My upper manifold gasket was leaking and I had it replaced. Now it leaks worse. on 1999 Oldsmobile Intrigue

After it was fixed, My car stalled while driving. I found a hose which looked like a vacumn hose up under the lip below the windshield washers. Then they said my catalytic converter was bad and then after that my mass air flow module. I had no issues other then the leak before I had the leak repaired. Now I have a P0442 OBD-II coming on.

The plenum needs replaced, the whole plastic piece. O'Reilly's carries a Dorman replacement. If they only replaced the gasket, it will not hold.
