as you can tell, I'm out of it.

No worries. Would be kind of ironic if it ended up being the problem.

Here is an example of a conclusive MAF test. How To Test A Bosch MAF Sensor - YouTube

The test of unplugging the MAF is an indication, not a sure thing. This test indicates a bad MAF if the engine smoothes out when the MAF is unplugged. This test is only applicable at an idle, has nothing to do with how the engine runs when taching it up.

Regarding the bad cat suggestion some of your symptoms, like the bogging are similar to a bad cat. Many times if you get under the X listen or jiggle them a bad cat will rattle. My experience has been that the are either good or bad, they are not intermittent or change based on going or coming from work.

Regarding vacuum leak suggestions. There have been times when I have gone over the same possibilities looking for a vacuum leak and concluded there was none, checked everything else that I could be sure of and ultimately went back looking and finding a vacuum leak. I never know when I have done enough to be sure there is no vacuum leak. I am not saying you were not thorough.

This is a great video suggestion. I know you have replaced the fuel filter but running these tests would be easy. If you do all of the tests you are up to date on what is going on at this stage.

If you pass in flying colors that would be distinctive progress.

One of the posts you made earlier today was referencing your video--the engine was running fine. In the video you said you had not tried hard acceleration--do you know if it ran fine under hard acceleration as well?

it runs fine if I slowly accelerate. if I push too hard on the pedal, it bogs.

It's bogging down when you mash on the accelerator because according to the video with the gauge at the fuel rail, the pressure in the rail is going down. For some reason the pressure is going down when you mash or snap rev the throttle. The pressure should increase about 5 psi when you mash or snap rev the throttle.

I would check the vacuum line from the fuel regulator to the f connector at the intake boot. If that checks out with no leak, get a vacuum gauge, remove the line to the fuel regulator and connect the vacuum gauge and see what type of vacuum you get when the engine is at idle and what type of vacuum is present when you mash or snap rev the throttle. The vacuum should go down when the throttle is snapped rev or mash. If everything checks out then you may have a clogged fuel filter.

You can also check the fuel pressure at the rail and then remove the vacuum line to the fuel regulator either at the regulator, or at the F connector in the intake boot. The pressure should go up. If it doesn't you may have a bad fuel regulator.
