Exhaust and Knock Sensor on 1999 Infiniti I30

How do I replace the Exhaust Gas Recurculation Flow Malfunction and Knock Sensor? The check engine light is on due to these issues, so any immediate answers would be helpful.

expensive guess for egr. are you sure it is bad. a lot of issues can cause this code that are not the valve. forget the knock sensor code. it will not return once the flow code is resolved. Roy
