Before U blow Ur cash on new sensors/cats or anything, try putting a can of one of those cleaners like CRC's "guaranteed to pass" thru it, reset the codes and check again, -may be able to clean up the O2 sensors / cats now that everything else is ticking.
That is a good idea, but one that I already tried. When I cleaned the upper/lower intake manifolds and got everything back together, I injected some of the carb cleaner with the car running to further smooth things out. Reset computer, drove again and light came back on again. I just think that it's odd that the car will run exactly the same with and without the MAF unplugged. Runs fine - but pig rich.
