What is your question?
How do I know which oxygen sensor to replace. Or, do I just replace both at the sametime? Also, can I clean out the egr valves myself
What makes this problem better or worse?

*Hands-on* TESTING required to determine if sensor is defective or there is another operating error that the sensor is detecting - just like it should. Yes the EGR passages can be cleaned.
