The other night I started hearing a strange noise comming from the engine area. It was only at a certain point as I was going to shift. It sounded like either the header springs were viberating or a supercharger when you decelerate. After doing some looking around I finally found the problem. It was a vacuum leak at the vacuum port gromet on the power brake booster. It seems that only at a certain point the engine viberation or movement would allow the leak to occur. I guess I'm going to get some black silicone and make a small bead around the gromet where the plastic fitting goes into the booster unless someone has a better idea. I also found that's why my idle speed has been somewhat erratic.
Just thought I would let you'll know.
