More issues! whoo-hoo! Whenever I'm on the throttle (cruising) the power will cut out and the revs will drop. As soon as I prod the throttle, it goes back to normal... until I let off again. This happens only when the car is cold. The knocking noise also goes away when the engine is warm. This leads me to believe that its a small hole somewhere that's causing all of this and it simply closes when the hot metal expands. Thoughts?
