Nope. It does not "lean out" it just stops running. I also ran this setup for about two years prior to selling the car.

The engine took the same amount of time to die as turning off the key. attributed about 10% of my gains on the civic to this mod alone most of the rest to the MPGuino. (Had this and a grill block on the civic)

I used it in pulse and glide, coasting down hills, Any slight down hill (you would be amazed how many you find when looking), Any bend in the road you would naturally slow down for, etc.
