If the vehicle is marginal already, yes the effect could become enough to
push you over the edge.  Personally I always keep my vehicles in the range
where I donšt worry about being close to the edge.  If you are close enough
for it to have an effect, you need to look at the major causes of nox
failure. Cat converter and timing and air leaks causing lean burn.
