Yes Steve, Dave
-looked there and the entire air intake is air-tight. I just finished swapping a AFM from a friends vanagon- still the same. I thought so.
Not an AFM problem.  
 I The one thing that stands out now loud and clear- the engine can't take a load. It will idle and rev smoothly-as soon as you put a load to it that is let out the clutch, it revs-cuts-out over and over again. If you do it very gently you may get three blocks before it happens again.  

So now I'm trying to figure out why. What is the engine not getting that it needs- it has air-fuel spark- ? I'm going to look at the fuel supply again. Load demands more fuel- if the pressure is dropping, then maybe the fuel pump is bad. I put a bottle of Heet.

Maybe large filter is clogged- anyway- I'll be looking at it all closely.
Won't be til Sunday.  

thanks-

I'm not sure what set up you have in your '82 but I'm assuming its an inline 4.

My son had a similar bucking problem with his Jetta and it turned out to be a tear in the boot that goes over the afm.    Every time he pulled away, the torque reaction moved the engine and opened the tear, making the mixture lean.  It took a while to find the problem because the tear wasnt obvious when we took it out to check and then we dismissed it for a while.    His was using the CIS fuel injection system, with spark knock timing, not that this would affect the result.
