AFR issues

Few Q's since I think I found the air leak in my 2000 234/235 hybrid letting air in just beyond the turbo.

The AFR now bounces at idle ( from 14.5 to 15.5 sometimes up to 16, I remember it being rock stady before ( I think) I cleaned the MAF with MAF cleaner before re-assembling it.
ALso is it suppsed to go all the way up to 18 when you are coasting? and it hits 16 every once in a while after slowing and dwownshifting, normal?

theres no way your afr was steady at idle, unless like most wide bands it puts out a steady reading while warming up.

cruise on throttle will most likely ve very close to stoich.

snap off throttle wouldnt be very odd for it to go lean momentarily when the injectors shut off.

but ive never had a wide band on a saab.
