Thanks to all who replied, I replaced the BPV today $47 and haven't had the
problem yet (short test drive, but I could make it happen on demand before)
car also feels much better. Less turbo lag, and it seems like more boost.
Just for fun I tried blowing through the larger openings on the old and new
valve, and found that I couldn't on the new one, but could on one of the
openings of the new one.

Symptoms are classic for a failed TBV (turbo bypass valve) to me. Check
Scott M's site regarding replacement. Not too expensive and quite easy to
Regarding likely fuel pump noise-- when in California in warm conditions
(~90 or better), our pump buzzed as well. I believe it's their gas mix down
there, as symptoms disappear up in the Oregon/Washington area. I've heard
some have tried adding a small amount of auto trans fluid to the tank to
help lube the pump.
