Question Trouble codes and check engine light

Hi everyone,
Can you please let me know if there is a better place to post this?
I have a 2009 Pontiac G8 with about 84,000 miles. I just threw a boatload of codes today and I am baffled.

Has anyone ever had these codes all go off at the same time?

CODES: P0306, P2271, P2270, P0327, P0300, C0561.

STABILITY CONTROL OFF flashes on the idiot panel, ROUGH IDLE, ROUGH ACCELERATION AND IT FEELS LIKE THE ENGINE VIBRATES A LOT.

SHOULD I DRIVE IT IN OR HAVE IT TOWED INTO THE DEALER BASED ON THESE CODES?

I currently have an exhaust leak in the resonator and have a new exhaust system that was just delivered to my house today.

The car has lost its power and feels like it did when the valve lifter blew up around 40K miles.

Any help would be greatly appreciated.

Thanks,
Bob
