I need locate the vacuum hose for my c280. The reason that I am asking this is that I got an oil change and believe that my vacuum hose has been disconnected. This has happened to me before and I don't want to go back to the repair shop and would like to do this on my own. Any suggestions?

thanks!!!!!!!!!!!!!

If you're car is running funny after an oil change, I'd really take it back to them and complain. It might be something much more complex than a vacuum line and if you start trying things then they're likely to say you goofed something up.

If you want to proceed, however, and you're pretty sure it's a vacuum leak, know that there are several vacuum hoses under the hood. The easiest way to isolate it is to take a length of hose (vacuum will work) and slightly insert one end in one ear. Remove the plastic engine cover and then with the engine running -- be careful not to catch you, your clothes or anything else !! -- you can move the other end of the hose slowly around the engine. The hose will work much like a stethoscope and help you locate the hose. (You'll clearly hear the hiss/whistle when you're close to it.)

Good luck and enjoy the ride,
