I've driven nearly 160k miles on this wonderful car. Lately I've noticed that the cruise control, when activated, allows the cars speed to drift up/down a few miles per hour. I'm thinking it may be a vacuum leak as I also got a code yesterday (0172) after the 'check engine' light came on. The car runs fine, and I've begun changing some of the smaller vacuum connectors, the 90's pieces that flake apart when touched. Should I look elsewhere also for this possible leak? I've been to my dealer and they cannot even show me an up to date fische that contains the same vacuum layout of my vehicle. (Has Volvo always been this bad?)
Your help and input is greatly appreciated, as I would like to drive this car at least another 150k miles if not more.
