Where is the egr valve located in my car? Also if my engine knocks because i'm using a lower octane fuel will retarding the timing take care of the knocking or should I just use a higher octane fuel?

You dont have to touch the timing at all, over a few drives if there is any problems the knock sensors will pick up on it and will inturn have the computer retard the timing.

Id run what was suggested due to the fact OF if you run it with lower grade and the timing retards, the amount of loss in performance and fuel mileage will outweigh the cost and performance of high grade.
