Hello there,


I am new here so not sure if I could post a new thread or had to use the search engine, so forgive me if I did soemthing wrong.


Yesterday my CL600 caught some kind of a problem, maybe if you read it, you will be able to recommend me something.


When I start my car, I can easily drive and there are no issues with it, but if at some point I take it over 3k rpm, the car starts to vibrate horribly. When I let go of the acceleration pedal the vibration is gone but at any moment when I touch it again the vibration is back.


If i stop and restart the engine, the vibration is gone and I can drive without any problems until I take it over 3k rpm, then all the same problems are back agian until I restart once again.


Any ideas what could be the fault? Sparkplugs? Coils? Something wrong with the ignition?


Thanks.

First check transmission mount it's the cheapest and easiest fix

But it does sound like a misfire and coils are the first suspect , followed by plugs and wires

Any warning lights on the dash?

Sounds like coils or engine, trans mounts

You will most likely need new engine mounts. I had a similar issue when I first got my CL, replaced the transmission mount but the vibration persisted. When I was having ABC hoses replaced, tech noticed that engine mounts were cracked so I had to replace them. After that vibration was gone. You should also inspect your front struts. They are under a lot of stress and - depending on mileage - they can "crack" (top piece cracks and even separates from the strut). This won't give you ABC message but it can contribute to noise and vibration.
