I tried searching but the keywords are way too common to get any results.. Anyway, ever hour or so of driving the car will have a "moment." It will run on a fast idle out of nowhere and at the same time makes a howling sound. I remember a couple years ago trying to trace it down and it sounded like it was coming from the airbox area. A simple tap of the accelerator will clear it up, the idle will instantly drop back down to a normal idle speed and the howling goes away.

Any idea on what would cause that?
