Knock sensor/o2 sensor/engine cleaner Q's

1) What does my knock sensor actually telling me when the check engine light is on? Cleared the code and it came back 2 days later

2) when using code scanner for the check engine light, the scanner one O2 sensor was running rich and the other was running lean--should I warranty these two out.

3) anyone know of a good motor cleaner--like sea foam???
