scroll to the bottom of the link and you'll see some photos of its location and the screws and tools you wil need. Just grench that MAF in MAS AIR FLOW cleaner spray and let it air dry and DO NOT blow on to it, that will create a fog on it.
Just shake it around to let out any puddles of the cleaner stuck in the sensor and let it air dry for for 5 minutes then reinstall.
