my 83 300D did something funny today.

when i was driving home, the power brakes went out.

then, the tranny started shifting harder (but not as bad as a vacuum line completely disconnected - i've experienced this too).

when i tried to shut the car off i had to open up the hood and do it manually.

the funny thing is, i think the power door locks still get vacuum.

i've searched the forum and got some valuable information, but i was wondering if anyone had any ideas about my specific situation.

also, i checked the vac. valve on the injector pump. i don't know it's name but it's the one bolted on to the ip and i can't tell if it has oil on it or not. there is some black stuff that looks more like rubbing from the hose, but it could be oil (?).

any help is appreciated.

thank you
