Did he reset the computer after the replacements? If not it needs to be done then drive as you normally do so it can relearn your vehicle and the way you drive, this usually takes about 20 minutes drive time, during that time if the check light comes back on then it stops learning as there is a hard fault in the system. There is an actual mass air flow cleaner out there and as you use it with the sensor cold it won't harm even the "hot wire" sensor.

he did reset the computer checker that he got the code from, if thats what your talking about? and i did drive it so it could relearn, still nothing, what do you mean hard fault?

A hard fault turns on the check engine light. That sounds like he just cleared the codes, he needs to do a full reset.

Depending on why it's doing this it may need to be programmed. you can get the dealer to do a zero throttle re-learn, idle air re-learn and other things to get the idle down. may also have ruined the throttle body but have to get it checked to be sure. the code for mass airflow doesn't mean to replace it could be wiring, ecm, etc.
