Default p0172 and p0175

i just got these codes today and the last time i had it was over a month ago. when i last had it i cleaned the maf sensor, reset the lights and have been good since then. i also recalled the "MIL" saying it was on.

so what i did today was quickly checked the codes since the light came on and low and behold same codes. so i reset them again. has anyone had a solution in fixing these? i did a search on this already and most always say its clean the maf sensor... any other solution?

ok I had this problem ever since I put on the AEM intake with that ETI chip. I want threw 2 sensors and same thing would pop up once in awhile. its deff a MAF problem. or rare problem would be the egr valve being stuck open. there was a TSIB for the IS250s on this...
