Ok..I have been getting this combination of codes..first..I got the Lean bank codes..1 and 2....Now Along with these I'm getting the EGR Low Flow code....seeing how those who delete the EGR are sayin' they get detonation sometimes at light throttle....Can the EGR be primary reason for lean bank codes?

thanks

 

Check the vacuum line that goes to the top of the EGR valve. They are bad about hitting the EGR tube and burning a hole in them and will cause just what you stated.

I did away with mine
