[s-cars] New faltering problem

[calvinlc at earthlink.net]

This is interesting.  This is EXACTLY the same behavior my A6 had.  I kept
taking it back to the dealer because it was under warranty and after giving
me all sorts of bogus advice (lower octane gas, etc.) they finally agreed to
flash with the latest programming and what do you know, the problem was
fixed :)  Obviously yours isn't software related but it's just funny that
the same problem can be caused by completely different means.

Hi Y'all,

A new (to me anyway) problem has reared its ugly head.  So far it's not too
bad but I don't want it getting any worse and it is a bit of a safety
hazard as well.

The patient:  95.5 urS6 w/ RS2 mods, etc.

When the engine is cold-cold-cold on first start-up it fires and starts
immediately and runs just fine until I start to add a little power to pull
out of my driveway.  Then the engine falters and feels like it has some
sort of fueling problem.  By declutching and getting on the loud pedal a
bit it will pull for a bit and then falter a bit more.  This lasts only the
first 200 feet or so and then all is well and the car runs absolutely
great.  It definitely feels like a fuel starvation problem rather than some
sort of ignition problem.

This behavior, due to the location of my driveway entrance in a nearly
blind curve in the road, is more than just an annoyance.  I need to be able
to get moving NOW to get out of the driveway while the way is still clear.

I have not tried letting the car idle for a minute or two before pulling
out.  I'll do that this morning.  Perhaps a little warm-up time might help
the immediate problem and provide another clue.

Cold start valve?  If so, where is that mutha?  Other suggestions?

Bob
