Follow-up report: car repaired successfully
Issues:
No power
KOEO codes 181 and 189
KOER codes 159 and 225
Cylinder balance test fails #2, 3, 4 & 6
Well, We (Mike & I) fixed the car today. Turns out clogged fuel injectors were
the culprit. The little screens were actually
clogged with crudd. The clogged injectors fouled the plugs, which in turn sent
the O2 senders into fitts. We installed fresh
injectors, new plugs, a new Magnaflow Y-pipe and used (but known good) O2
sensors. No more CE light and the car runs great.
Now to tackle the heater/defroster issue.

I already replaced the vacuum hoses. The MAF connector feels nice and firm.
For some reason, I really have a feeling that it's the cats. Just a gut
feeling from the way the car acts. It idles nice and even.
Once warmed up, throttle acts normally while not in gear, but any load (reverse
or forward gears) makes it act like the timing is
way off (lots of stumbling, sputtering and lack of power).
I could really use a second set of eyes looking at this one.

Robert:
Unplug the MAF and see if anything changes. Might just be the MAF
connector. Ford had a recall for some of these connectors. Build internal
corrosion and cause high resistance. New ones are available from Ford.
Vacuum leaks can cause a super lean condition. Check the vacuum hoses
carefully. It's a very old and high mileage car. The rubber will be very
hard and brittle.
I think your cylinder balance test is off because of the other problems.
Finally check the fuel pressure. Is the pump loud?
