Default Way to test MAF?

The TPS adjustment fixed the trans shudder in 4th while tc is locked... for a week maybe. Now it seems to be once again very prominent.

Some days the car runs tip top, meaning I step on the gas and my had just sits back in the headrest and feels the power. Other days, I have a problem pulling past a '95 civic like last night (though I did come through in the end). Some days I touch the throttle, and it doesn't even have to unlock TC to feel power, other days I need to nail it to the ground before I really feel anything moving.

I'm wondering if all this is able to be pointed at MAF? Something is going on... and I have a feeling it'* a sensor. The trans shudder has existed in the previous 4 transmissions/TCs. I would like to do a complete sensor check, whatever it takes.

So is there a way to test MAF?

EDIT: I forgot to mention... it'* getting to the point where I'm spending 60-80 bux a week in gas. That'* for like... MAX of 300 miles of driving. Probably more realistically, 200.

You would need a good oscilloscope (I'd think) to test a MAF, as it puts out a waveform rather than a voltage.

I've got a known good MAF sensor off my '98 LeSabre'* original TB you can swap in for testing (if you want to pay postage).

It'* been cleaned before, when I did LIM/UIM/TB clean. I'm going to call out the o2 for now, as it probably has the 92k mi that'* on the car.
