Most of the time my car has no vacuum issues. Everything works as it should, at least as far as I know, and the doors will lock/unlock about 5 times, which is what the owner's manual says they should do.

In the last couple weeks, though, the car has occasionally taken a while to shut off when I turn the key and after that I have very little vacuum in the central locking system. But without doing anything at all I can start the car, drive it around, and it will work just fine the next time I shut it down, and the locks will be fine as well.

I can track down a vacuum problem but I can't do it when everything is working right! Are my issues symptomatic of something? Is my shut off valve dying? I know that someone out there has had this same problem so I will await enlightenment, although I think I will see if the white bleeder thing atop the IP will hold vacuum in the meantime.

Thanks!
