I have had the exact same problem from time to time.  My engine has only
been steam cleaned once, and the problem had appeared long before & since.
I have had both Al Blanchard (Audi & Porsche Specialties), and Scott Mockry
(SJM Auto-technik) look at, drive, and experience the symptom.  I have
cleaned the MAF terminals & even replaced the MAF.  After such, the symptom
goes away, but will appear seemingly at random.  From various threads, I am
going to replace the K&N with an OEM filter & clean the MAF of any oil
residue.  If no results, I'll replace the WGFV.

I had the same thing happen on my S4 after cleaning the engine bay. IIRC it
happened at any boost level. Went away after a couple days. I never did find
any water contamination, plus it doesn't have a distributor! I imagine the
water could get in any number of connections that feed the ECU. Don't you
just love problems that fix themselves..;-)
