Even though the P2198 O2 Sensor Signal Biased/Stuck Rich (Bank 2 Sensor 1) populated. Could that code simply have been the EGR tube?

Yes, it can because the EGR can affect the mixture if it leaks. Have you installed the new one yet?

Good news, I would clear any codes and then just drive it to see what happens. Did the code come back since the repair?

After I replaced the EGR tube, I cleared the codes. I drove it an hour away then an hour home and when I was driving an hour out, the check engine light came back on. When I got home, I ran the scan again and that's when the o2 sensor codes came back up. I don't have time at the moment to take care of the o2 and the fuel injectors until the weekend.

Okay, let me know how it goes, do you hear any exhaust leaks while it is running? Also, does the engine idle smoothly?
