Q: Exhaust and Knock Sensor on 1999 Infiniti I30

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
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.
