hey if you truely think it is your egr valve unhook it and if that is the problem then when it is unhooked it should run better and the codes should not come up. hey if you cahnged the 1 o2 sensor and not the other you probably made the code for the one u repalced come up again. i would recommened that you change both of the o2 sensors at the same time. try checking if your catalatic convert is plugged. how you do this is take a dollar bill and hold it at the end of your tail pipe while it is idleing and if the dollar bill stays still you have a plugged catalatic converter.

Performing a GM OBDII Driving cycle:
Do not leave the key in prior to the cold start or the heated oxygen sensor diagnostic may not run.
SOURCE: saturn code p0442, evap system small leak, can't find leak
I would send the car in for a smoke test...So much easier to find the leak...
Testimonial: "found another definitation for a code 422. replaced rear o2,fixed"
