[s-cars] New faltering problem

[Robert Myers]

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
