I have been on this site for about a month now and it seems that there are a host of vacuum problems that can occur. Today, I had the first for my 300D. I changed the oil yesterday. I accidentally popped off the vacuum line that goes into the back of the Injector Pump. I heard a slight hissing sound even though the car was not running. I reattached it. Then I started the car and idled for a bit to recirculate the oil. After a while, I went out to dinner with the family and I noticed the vehicle was much more sluggish from a stop than normal. Then today, I noticed that it won't turn off and the door locks are not working. If the car won't shut off AND the door locks don't work, does that mean that I just have a leak in the system or is the vacuum pump shot, etc.??? I am a light to moderate DIY'r but vacuum systems are foreign to me up to now. HELP!!! I feel sure whatever it is I can fix but getting the coathangar through the firewall to shutoff the engine just doesn't work too well!!

Also, I installed today a glue in dash cover. I noticed the air temp sensor on the dash was not meeting the recepticle like it should so I dug around from under the dash and pulled out a rubber tube about 3/4" diameter with a white plactic housing at one end. That is where the air temp sensor is received but I cannot find the electrical part that goes with it.

Sorry for the many questions but the Haynes manaul is blank on me for this one!!

Thanks for the help,
John

John: Lot's of help from this site on vacuum leaks. Go to the diesel discussion section and down a page or so find '82 300TD A/C problem. Ice Sailor's diagnostic writeup should help you locate the problem.
good luck;
