Search. I did this yesterday and found some solutions. Do you have a K&N? The oil from the filter could be crudding up the resistors in the MAF. Home Depot carries QD Electronic cleaner. That should work. (spray the MAF 8-12 inches away) Also could simply be a bad MAF sensor, or bad/broken wires to the MAF.
You need to know if the MAF is sleepy (low frequency out)
or dead (nothing out). Crud on the wires will make it need
less power (pulse frequency) to keep itself warm like RyanJ
says, and you may just be a bit below 1500Hz output and
fail the diagnostics (F-body lower limit). Zero output would
be either blown electronics, a busted sense wire or a harness
disconnect.
You can find digital multimeters now, in the $39 range, that
have frequency measurement. I found one recently that even
came with a thermocouple in the package too. For these cars
this is a must-have tool. Too much electrical stuff going on
to work blind.

I'm having the same problem. I tried the spray and that didnt work (it did help slightly with my car's missing) and I swapped maf sensors with a buddy's f-bod. That wasnt the problem either. Anyone know where I can find a lamen's guide to walk me through checking the wires?
