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.

Well the biggest problems for the 98 and 99 cavaliers are that they mess up from the timing chain,..they make a rattling noise on the right side underneath the fender.

Drive it. Then have the rear abs brake sensors checked because they seem to be the first to go in a system like that. Someone with a scan tool should be able to read out any trouble codes in the abs system

Check for vacuum leaks. Spray some carb cleaner or WD40 around the intake manifold, trottle body and any vacuum lines. Check for loose connections on engine wiring harness (Maybe you disconnected a sensor, and forgot to re-attach it?).
