I had the same prob in my 91 GLI and it turned out to be a vacuum leak.
Start off by pressing on the top of the airbox (the round rubber "top" that
connects the airbox to the manifold) while the engine is running. if the
engine starts to 'choke' then you have an air leak. start looking at all
the vacuum lines. you can go to the local dealership and ask the parts
department to print out a schematic of all the vacuum lines so you know
where to look.
hope that helps.

Subject: [a2-16v-list] Motor mount questions
Seeing the list running again inspired me to ask (another..) question. I
had all of the motor mounts replaced on my 92 GLI last August by a
competent garage (German Motors in Providence, RI). After replacement, the
rear motor mount was found to be defective (how can a motor mount be
defective?)- the car had a lot of vibration on acceleration, and felt like
a tank. They replaced the bad mount for free, and the car was a whole lot
better. Fast forward to two weeks ago- I had new tires mounted at the
local Midas by my house (Goodyear GT-HRs). All of a sudden, the car feels
like it has a bad mount.. but not all of the time! Sometimes it feels
great, and then sometimes when accelerating it feels like a mount is
totally dead (everything rattles, etc). Looked under the car, don't see
any broken exhaust hangers, and no rubbing. Took the car into German
Motors, they said the motor mounts looked fine. Anyone have any ideas? I
would think that if a mount was bad, it would feel bad all of the time- it
only feels bad about half of the time. I'm still not convinced that the
exhaust is rubbing a little bit and I'm just not seeing it (it's freezing
up here- being outside under the car is something I can only really take
for a few minutes..). It's pretty annoying though, especially since I
spent a lot of cash on the new mounts.
Thanks!
Andrew
