The pump was installed about a month ago. Don't know the brand yet (don't have the car right here).

Have done a quick check for leaks and didnt find anything. Tried plugging all the other lines and just running one from the pump to the IP valve.. Maby I should do a more thorough test.

Is seems that the vacuum coming from the vacuum pump (20"Hg) is good, but the vacuum from the IP prop. valve to tranny is to low. Is there a chance that the prop. valve is leaking?

may be i should try to tweak the amount of air the prop. valve is leaking into the system by partially blocking the inlet line for the prop. valve??

Does anyone know what the vacuum directly from the vaccum pump is supposed to be?
