alright, i recently had a code for the upper right O2 sensor-i replaced it. about a day later i got a new code: 420. i read the answer for the cel, but what do i fix??? do i replace the other O2 on the right side? I feel a little less power also...i'm sure the two are related. anybody got any ideas? i need help!!

I would start with the O2 Sensors and Replace the Spark Plugs.. Then From There perform a full tune up if one has not been done in a while..
