SES light on

Okay I got 2 codes P0171 and P0174. Which is stating left and right banks are running lean. According to the troubleshooting manual if both these codes come on at the same time, it is the Maf sensor. This will be the third maf sensor i have put on this car for the same issue in the past 2 months. Do anyone know what could be causing this. Oh yea and the MAF has not been ported or descreened. Thanks
