P0133 is the heated oxygen sensor code and the P0341 is the cam sensor code. Saturn's however do not have a cam sensor, the problem your having is most likely a vacuum leak that is causing your RPM's to soar. Look around the engine for any broken or dried out vacuum hoses replace as needed. Do a thorough inspection on the ignition wires and on top of the coil towers for any corrosion, if corrosion is found replace your coil.
Note: If code P0341 is constant then there is a problem with the ground side of the ignition module.
