I don't think your problem is map/maf related.

There are a lot of people on the forum who are well versed with solving these kinds of issues. Oddly as many give you advice, you are either not able to follow it financially or would prefer to spend a lot of time going in a different direction. It's a bit frustrating trying to help you out on this issue.

When you unplug a sensor on a running engine it's about the same as you closing your eyes when you are running in the woods. You'll stumble and try to catch your balance, as will the engine. By unhooking sensors you have to expect that the pcm is missing an input that it's used to seeing. So it'll compensate the best it can.

Free for you to check:
Pull the spark plugs, do any look significantly different than the others?
Look at your spark plug wires, do any have a mark on them where they are laying on/touching metal?
Start motor at night and mist the engine with water, see any sparks jumping around?
