I would use electrical contact cleaner on the MAF. You want to clean only the very delicate filament of wire that protrudes from the sensor into air intake tube. If you remove the bed to work on your filler tube you will need your JB Blaster to soak the bolt threads(if accessible underneath) to make things easier as they are probably rusted in place. Might want to give them repeated sprays in advance of the day you do work to give it time to work in the threads. Also think you will need a torx head socket to remove them.I read that it is size T55 torx . Am sure someone here can clarify that.
