"Blowing Bottle" Noise From Fuel Filler Area

Thanks in advance for your help! My vehicle is a 2000 Boxster 2.7L.

My issue began with the infamous noise from the fuel filler area that sounds like someone blowing over the top of a beer bottle. The noise was fairly continuous at slight acceleration around 2500 rpm and would stop with throttle change. After much research here and elsewhere, I elected to change the two purge valves in the front passenger fender area (P/N 996-605-213-01 and 996-605-201-01) along with the fuel filler cap. This did not resolve the issue.

How often would you suggest taking my 09 caymanS out on the open highway? I do alot of city driving and recently after letting the car sit for three weeks or so it was hard starting, after i got it started it was rough idling for a while. No warning lights just a rough idle for some time. It normally starts right up.Thanks, Greg G
