If you let off the throttle no fuel will be injected. This is normal.

Perfectly normal, Think about it this way, AFR's are your air to fuel ratio, when your deaccelerating, almost no fuel is being spit into the cylinders, when your flooring it your afrs will go down (12's) this means its running richer as in more fuel, when deaccelerating theres no fuel so 215 means there is a shit ton of air and very little fuel aka lean
