I had the same issue with mine as well. I replaced the MAF with a Hitachi one and still had the code. Reset the computer doing the pedal dance and drove it around a bit. I also cleaned the TB using some spray (did not remove or touch the TB, literally just sprayed the hell out of it

). Haven't had MAF code thrown for a few months now ::knock on wood::
1. Turn ignition "ON" (without starting vehicle), count to 3 seconds.
2. Depress/Release accelerator pedal 5 times...hard and fast.
3. Count to 10 seconds (not 7!) and fully depress accelerator pedal.
4. Count to 12 seconds (SERVICE ENGINE SOON should be blinking), release accelerator pedal.
5. Count to 10 seconds, depress accelerator pedal.
6. Count to 10 seconds, release accelerator pedal.
7. Turn off ignition, then start engine. Done!
Not sure if you'd like to try the above. Worked for me.
