I have a 2003 Nissan Altima 2.5 4cly. My maf sensor is located near my battery. It's the part that connects to the air filter. It so simple, you can do it yourself. and without getting dirty.lol Also what they're not telling you is...if your car has not stopped running, is that you can purchase maf sensor cleaner. and it works. my husband used it on his truck, and did not have to purchase one. They sell it at Auto Zone, NAPA, Advanced Auto Parts, etc. Try it ! Good Luck !
