Having some trouble with the vacum system holding pressure it seems. The (all) door locks will not open when the car is cold. Once the engine is running for a bit the locks come open. All of the locks close from the drivers door after driving the car. Not a major inconvenience for me until multiple passengers are in the picture. I plan on replacing all of the rubber vacum line intersections & termination pieces for starters. Any other thoughts?

If you have a California or Federal version without the black box, like me, you might be kinda lost.

Try this, I'm going to today.

The thread that "benchracer" has for you is sweet. I used that one to track down multiple vacuum problems on both my 300's. Worked very well and the golf tees were the best part!
