I'm not going 'all out', so don't worry. Just wanted to know if the cause could be something that could leave me stranded, that's all. By the way, vapor lock is highly unlikely but possible, I guess; my question then is why it didn't happen before, with higher speeds and ambient temperatures?

i dont think that helps, really, but i wouldnt go crazy about it just yet...
Hey man, that HELPED A LOT, because at least I know it's something 'normal', as in the car shouldn't do it, but many do, with no problems (the M3 has a lot of weird traits like that, like clunking noises, etc). I've never read about that issue before, so I'm glad you chimed in for others who might experience it as well . I have to say it's possible my car has done this before, but never noticed it, since I usually have the stereo on, plus I'm not constantly glancing at the instruments for the TPMS symbol , like I was on this trip due to my plugged left rear tire.

Having said that, I'm curious what it is. I say it HAS to be the idle valve, but maybe it's just a peculiarity, and not an indication of impending failure. We'll see. Thanks again to all for your contribution. Have a great day.
