I have a really odd kind of reving soud when i first drive off EVERY TIME. when i leave in the morning i start my car and let it idle while i finish getting ready for the day and when i first pull off it makes an odd sound ??? its almost like sumthing is starting up ??? i think its my ABS or sumthing to do with it bcuz if my foot is on the brake when that sound happens then the brakes kick in and stop abruptly ??? anyone heard of this ???
