Hey guys I have a 97 maxima auto I have the p0400 egr and p0325 knock sensor bank 1 code...

my my question is will the egr code make the knock sensor code pop up? I was on maxima.org researching and some people say it does and some say it doesn't ..

Whats is my best course of action ? And is there a mechanic In The area that wants to make extra cash to fix? Email me bstr8upballa@gmail.com if you can fix..
