Why do you think it’s the oxygen sensor? Does that seem like a good guess? Well, it’s not the problem.  
Is the check engine light on? If it is, have a mechanic scan it and determine a course of action (troubleshooting).  
A fall off of performance is, often, a result of loss of fuel pressure/flow. Change the dirty fuel filter, and check the fuel pressure. After that is done, there are other checks to do. Let us know.
