[BiturboS4] Re: more hesitation... after a cold start..

[Aurangzeb M. Agha]

Hi Nicholas --

While I had my '01 S4 (stock) in Athens, Greece (now I'm in Boston), I was
noticing the same thing.  In the evenings, the air got pretty chilly, and
I thought that was it.  What kind of temps are you realizing when you
start your car and notice the hesitation?  Does the car respond
differently if you start and run in warmer air?

I found that when I moved to Italy, where the climate was a bit warmer,
the car would start and run fine without any hesitation.

Another driving factor might be the quality of the gas you're feeding your
baby.  Greece is notorious for having filthy gasoline, no matter what
octane you put in.  Italy (land of Ferrari) on the other hand, has much
better quality gasoline (it's also twice as expensive!), so that might be
a factor.

Try putting in high-octane gas from a source you know to be clean; for
example, a Chevron or Shell versus a corner gas-store, and see if that
makes any difference.

Good luck.  Keep us updated.

	Rgs,
