Apparently my mass air flow sensor needs replaced. I have priced them at about 140.00. At this price, I would like to do the repair myself. I would like to know if anyone else has done this repair and if they encountered any issues doing so? I was told by a mechanic that it is a difficult repair(I think he meant "for a woman") and that it should be done at a shop.

 

It is not difficult to replace a MAF sensor. Depending on what exactly is broken it could be difficult to actually "repair" a MAF sensor. And that would be independent of the technician's gender.

But I would not trust the opinion that it needs to be repaired or replaced. Maybe it is just dirty. You could take it out and use a can of CRC MAF sensor cleaner and spray it thoroughly. The most important thing is not to touch the actual sensor wires with the hands or any object other than the spray-on solvent. Let the parts air dry and put everything back to gether.
Check out the Haynes manual on the MPV at your local library or buy it for $20 at the parts store. I am sure it tells you how to take it out.
