Mass air flow, map sensor, vacuum leak or leaking injectors can cause it of they all say rich either you have bad o2 sensors even though you replaced them doesn't mean they are good. But I'd you create a vaccum leak see if they change to lean. Also the ambient air temp can if it is reading that it is freezing temperatures and it's hot outside
