Ok, what you have is a kind of a "Flooding" feelling at low rpm, no
acceleration, i'm i right?
You swap the AFM with still the same problem, ok, let's eliminate this one
(assuming that the connection to this one is good!!! yea, wiring harness
problem, very common!).
It's NOT the cat... you would NOT reach cruising speed!
CHECK THE FUEL PRESSURE!!! PLEASE!!!
If ok, you can remove a lot of parts from your problem list and it mean you
have a "firing" problem (it could)or an electronic/electric problem (i doubt
it).
Swap distributor, it feel like you may have an advance problem (yea, even if
it's electronic, all engine have some kind of advance control)
Exhaust leak will NEVER create that kind of problem, forget about this one
for now.
Forget compression test, it's NOT your problem. You would feel it at freeway
speed (you said everything was ok at that speed)
You ask about the temp2 sender:

The blue one.
It's located on the thermostat housing, 1.9 and 2.1. I don't remember your
engine. If 2.1L, it's on the far left/front (on the head - left side of the
TH), on 1.9L, it's on the left rear, near the engine temp sender. It's also
blue.
I still think you have a fuel pressure problem.
Any kind of smoke???
Engine: fire, fuel and air! One is wrong.
Sadly, i have seen a lot of electrical/FI problem creating a lot of strange
problem.
But i would do 2 last test before you go to a shop. Swap the distibutors and
check fuel pressure. After, if that doesn't work, go to a good Vanagon shop.
Cheers, Benž
