Does anyone know the weight of the A8 4.2L V8? Fully dressed is
preferred. Engine + trans ok too. 
Much appreciated; Thanks,
Andy

Clean, part disassemble if need be and reinstall.  Use new O-ring kit
available from
dealer.   Replace O2 sensor if still having problem

CIS-E3 DPR current occillates around 0, so current  may not be
detectable if near Stoich
at idle.  Best to have idle mixture set slightly lean so DPR has to
compensate and then
enrich ever so slightly for best idle ? not over ? turn from lean side
of good idle.

Thanks a lot! Now I went to the junkyard and pulled a DPR from a car
there.
I was thinking about pulling the whole metering head/air flow plate
thing, but it was
just too messed up with connectors left open etc, so I left it alone,
only got the DPR,
which was not messed with like the one I had on my car.

I installed this, and now the car feels a lot better and has got almost
perfect CO
content. But when driving, it's too lean. The car lacks a lot of power
and feels like
it's slightly missing. If I try going up a hill in 5th at about 60 mph,
it almost won't
keep the speed.. I tried richening the mixture almost 1/4 turn, but that
was far too
much. Tried 1/8 turn and did not feel very much difference at all. I
have the Bentley
manual and will try all the measurements there, but it is kinda weird
that the car is
running so lean, but richening the mixture makes no difference until it
gets to 1/4 turn
and far too rich.. With the old DPR, the car was running far too rich,
CO content over
10%, but it had the correct power. Now it's slower than a school bus..
:P

I tried measuring the DPR current using some cables I made. I'm sure
they are working
and connected the right way, I set my multimeter to 200 mA, but I got
nothing except
0.00 anyway. Will the current stay at 0.00 all the time if the car stays
in open loop?

Vittorio,
If the alternator is one of those 110 amp units, then the two bolt pivot
is 
correct.  If it is the 90 amp unit, then it should have a long bolt and
nut 
at the pivot.  If you were to hook a long jumper cable directly between
the 
snubber mount to the battery ground, would you get a different reading? 
(The engine ground to chassis across one of the engine mounts may be
bad). 
You might also check the condition of the battery cable splice.
Cheers!

Ya, crank and rods are the same dimensions, but you'll have to bore out
.060
just to get to stock MC bore. You'll have to use a KH head as well; the
coolant passages are different. I know the oil filter housing is
different
(2 filters instead of one, but most likely you can swap in an MC
housing).
The oil pump's slightly different, but other than that not much else.
I've
run a KH pretty hard with forged pistons. Engine can take it, but the
fuel
system is another story.

Steve's got it right... often overlooked is the primary wiring.  Audi
didn't
use the greatest wiring when new, and now you'll often find corrosion
under
the sheath due to moisture wicking.  Remember, the alternator has to
have
the ability to get the current (amperage) out as well.

Another quick and dirty test is to check voltage at the battery versus
the
alternator post (if available when engine is running).  Set up the
wiring
before starting the engine.  If you see a voltage change (drop along the
wiring), you'll need some attention there.

Cheers!
Mark Rosenkrantz
