This one is a weird one and its the 1st time I ever get it....112----(trucks Only):Air charge temperature sensor below minimum voltage


173----hego sensor fault rich


177----hego sensor fault/always rich

My sensor are brand new. And BTW it was running rich on the wide band at cruising speeds. Usually in the 13's and 12's. That should the reason why??? I know why its running rich.
