Whenever I stop at a stop light, the car shakes. When the car is in park there is no shaking. Also, there is no shaking while the car is in drive waiting at a stop light, if I have been driving for awhile.

Has anyone has this problem?

might have warped rotors or uneven pad wear. take your wheels and and inspect the braking system

Thanks for the reply. About a month ago, I put new breaks, and rotors on the car. the problem was happening before I replaced them. I've also replaced all the spark plugs, because I read somewhere it could be that.

Sounds like gearbox related.. Any codes?

The only code I get is when I leave my car in park too long, and that's because of my O2 senor, that needs to be replaced.

Hmm i have a similar problem. When i come to a stop light, the car runs fine, but out of nowhere the engine acts like a load is being put on it, and vibrates real bad. It doesnt do it if I put it into neutral though. It's kind of like the a/c is being turned on full blast all of a sudden.

Is this likely to be a vacuum leak?

hehe, i used to have the same thing, and i did a lot of things till i found the problem... the engines mounts and the transmission mount, i change that, and now runs good.

+1 with motor mounts. Replaced them and shaking is gone.
Maybe you only need to replace the tranny mount, but if your engine mounts are shot, then the new tranny mount will die quickly.
Here's the thread about mounts replacement if you should need it: https://mbworld.org/forums/c-class-w...placement.html

Definitely look at the trans mount.

Sorry it took me awhile to reply. I replaced the tranny mount yesterday and the shaking is still happening. Should I replace the engine mount now? My dad said my idle might be too high, but I have never changed the idle. He wants to take it into the dealer to see if they will see what is wrong with it, but does not want to pay much for it.

find some youtube videos on how to inspect engine mount failure. If the same happens with your car then replace the engine mounts....

Change the engine mounts, again i really think that is ur problem, but remember buy originals
