Mercedes Benz repair: 2004 C240, vacuum leak, questionair

Question
Hi Ricky
I just bought a 04 C240 with 25K. Most of the time when I put on the brakes to stop at a light right before it stops it start to idle ruff and then almost stalls out. Can you help?
Thank You Very Much

Answer
Greetings Lisa!
It sounds like you may have a vacuum leak. When the car almost stalls,
your brake pedal should be getting hard to push. This indicates a vacuum leak and should be checked out real soon.
So it is possible that you have a vacuum leak or maybe even need a brake booster.
While this questionair helps many people in many ways, Sometimes you still have to have to go to your local shop or dealer.
I hope this helps and have a great day.Thanks, Ricky
