vaccuum advice?

[djugurba]

I'm trying to sleuth out a new vaccuum issue on the 300D and was hoping my symptoms might spark someone's memory. I didn't see the right reference while searching.

The vac line through the firewall to the back of the dash to the egnition cut off recently popped loose. I plugged it back into the hole, fixing the problem. but... now, even though the line is in it's hole it seems there is a leak because the engine will not shut off right away.. If I don't shut it off manually, it will eventually shut off after 30-45 seconds or so.

At the same time, the drivers side rear door is now unwilling to lock/unlock, and the transmission seems like there might be a difference in downshifting points. (though, this could be mental error, as I usually drive the sdl...)

it seems like a vac leak to me, but where can I start looking, and do you think the issues could be related to the same leak?

Thanks so much for your help!

the plastic lines are known for leaking where they slide into the rubber hoses and fittings. If one "popped" off it is probably not sealing now. Lots of vac leaks can suddenly appear on a 20+ year old car. If the driver's door is the only one with the problem, take the panel off and check the actuator in that door.
