Stalling after cold starting?

[Wesley Leung <wleung@interbase.borland.com>]

Hi gang,

Any idea on this one.  My 92 100S Audi seems to be fuel starved (or
something of that sort) when starting the car after sitting for a couple
hours.  It starts fine, but the second I give it some gas the engine acts
like it not getting fuel and the rpm's drop below 700rpm.  If I keep my
foot on the gas it sometimes chugs along before going up to 2500 rpm.  If I
stomp on the petal, the engine reacts and the rpm shoot up be it not very
smoothly.  The car didn't act this way when I bought it a month ago, now it
of course acting up more than a week ago.  I've used Shell, 76 and now
Chevron super and fuel injector cleaner but no cigar.  I have a feeling
it's has something to do with cold start mechanism shutting off when I
touch the gas petal.  Anyone else have ideas or should I bring it in to the
shop?

Thanks!
Wes
