Douglas,
I would put forth the proposal that the oil in the K+N filter has made
its way onto the MAF wires, thus altering the readings it takes to the
point that at idle it measures no air.  No air = no fuel signal, right?
(I could very well be wrong).  No fuel means it dies.
Others?

and the expensive new MAF.

Morning All,

On Saturday, while running errands, I had just started the car back up
after
driving to the mall. The car was idling while I put on my seat belt.
Suddenly, the engine just went dead.  It started fine, but then died
again.
This repeated about 3 times.  I finally kept my foot on the gas,
feathering
it when I had to come to a stop with the clutch in.  Made it home OK.
Sunday, did a few minor errands, no reoccurrence.

Today while driving to work at freeway speeds, it stumbled three
separate
times.  The check engine light flickered each time.

Now, here are the car facts and a couple of questions.  The patient is a

95.5 S6 Avant with 44K on the clock.  About 2K ago, I went to an MTM
Stage 1
w a K&N filter, installed by Anderson Motor Sports.  About a week after
that, I blew the turbo hose connection between the rubber hose coming
down
from the turbo and the plastic pipe that runs behind the front bumper.
I
had to limp about 60 miles home.  Was able to reconnect hoses the next
day.
No apparent consequences unless this latest issue is related.  Aside
from
the MTM upgrade, the car is bone stock.

Now the questions.  I have heard many talk about "pulling codes".  How
does
one do that without a VAG tool?  Any thoughts on the stumble?  I have
been
planning on installing new plugs and O2 sensor but have not done so yet.

All thoughts welcome.
