And I kinda wanna take a guess at saying maybe your cat is clogged with how bogged down it get beyond 1/2 throttle.

I dont think it does what does the ses stand for? (new pontiac owner) and you would think o2 sensors with the o2 sensor codes

service engine soon, check engine light
Well what do the o2 sensors do?
They monitor your emssions and air and fueling. So in turn they monitor the effectivness of your cat converter.
Go grab a pressure gauge and take the upper o2 sensor out and screw the pressure gauge in its place and start the car, if the pressure gauge read more than 1-2 psi your cat is clogged.
