In Levels select a point that you think should be gray and check the RGB numbers of 
the point.  Then double-click the gray (middle) eyedropper and type in identical 
numbers for the gray value you want there, e.g. R-128 G-128 B-128.

Close the box and then click on that spot with the gray eyedropper you have picked and 
set, and that spot will now be gray.
