my wideband at cruise shows it range between 14.5 - 14.9. it leans out between shifts upto about 18 and then corrects itself. in my case i'm pretty sure my maf is the cause of this as its reading a little low on the g/s. at idle it also can lean out as much as 17.5 and stay there for a while but i'm accounting that to the ecm doing this for idle fuel economy.
