I might be way off base with this, but.... could the "errrr" sound be coming on when the A/C fan kicks in? When mine does (off and on more than I like) my engine does sound different.

No, this noise sometimes stays on while driving in first through second gears. Sometimes making the engine sound REALLY loud inside the car. Not revving loud but like... ITS LOUD.. lol But if it doesn't stay on it always comes back on when it decelerates to its idle rpm - 1100 rpm. I was thinking its the A/C compressor. But when I turn it on it kinda sounds louder, don't know ... ergh....
Other times it tickles on and off. Kinda like..
Err... then Normal, errr, then normal... ERRRRRRRRRRRR, then normal... ERRRRRRRRRRRRRRRRRRRRRRRR... intermittently...
Check your surpentine belt tensioner and idler pulleys. That sounds a lot like mine did, and the bearing in the tensioner were destroyed. If it fails while driving you'll have a real mess on your hands.
