Posted May 16, 200816 yr comment_247661 I took the pipe from the brake booster off of the intake manifold and sucked on it. I couldn't make a vacuum, and I could hear the inline valve fluttering. Is my booster leaking, or is it suppose to work that way for some reason. I guessing the boosters got a rust hole in it and that would really explain a lot of things!

I'm trying to find the gremlins that are making my car run poorly.

May 17, 200816 yr comment_247732 Pinch the hose closed between the manifold and the valve and see if the engine behaves better.Or remove the hose at the manifold and plug the nipple.The hose may have a split in it somewhere.If the booster tank leaks then your brakes won't feel any different with the vacuum hose inoperative.

I'm guessing it has a small leak in the diaphragm.
