[QUOTE="cameron.rw, post: 426312, member: 18967"] The booster is definitely leaking and it has since I got it. When the brake is pressed you can hear a hiss from it. Maybe the reason from putting it in gear because I am on the brake. But could the brake booster leak be so bad now to cause this rough to almost no idle, along with the leak sound with the throttle. As of now to get it to idle I put the idle screw all the way in. then it cranks up to similar performance it was yesterday. But as you can hear in the video when i hit the gas quickly you can hear a vacuum leak and i'm not touching the brake. The slugish feel of the engine and at low speeds was there before it now becoming more rough [/QUOTE]
