Make sure your belts are tight. Check the clamps on the hose to the mass air flow on both ends. Make sure there is no trash or anything inside your air filter box. Is the car running ok?

You may have gotten some antifreeze on the belts, does the noise change with the engine speed?

i dont know what to do if your mass air flow sensor is out or out do it make that noise like something is stoping air from getting in that 's what it sounds like zzzzzzzz
Expert:  Richard replied 8 years ago.
They don't usually make any noise. That is why I think it may be something else. Can you actually say that is where the noise is coming from? If it is bad, you need a new one, but I don't want you to spend that kind of money if it isn't bad.

can you help me richard
Expert:  Richard replied 8 years ago.
OK, try taking the clamps and the wire connector off and remove the mass air sensor. Look inside and make sure it is clean, make sure there are no tiny holes or cracks in the hose. Then carefull put it back together and put a little bit of oil on the inside of the hose where it fits on the mass air flow. It may just be a small air leak. Let me no. I am going home soon, it may be tomorrow before I can get back to you.
