I have a 2000 gt with a 78mm BBK throttle body/ upper plenum. My issue is that at idle and just about any another time I'm starting to accelerate my gas pedal seems to have a catch in it. Like it's stuck on something for just the first half inch of pedal sweep. I have checked my pedal and it works fine no catching. The thing that makes me think it's vacuum is that the catch issue goes away when the motor is turned off. It does the same thing when I do it by hand at the throttle blade. Anybody have this issue or have any ideas of a fix? Thanks ahead of time
