Vibration driving me nuts!
2003 S55 AMG M113K Car with 111k miles
There is a very annoying vibration around 1500-2000rpm then above those or below those rpm's its smooth, the vibration is RPM sensitive and will do it in park not moving just revving the engine but does get a little more noticeable driving under load, its a very low frequency and when it happens its a "pulsing sensation" That you can feel throughout the car, I had a passenger actually ask me about it and noticed it while driving on a very smooth road, Like something is out of balance, ive been chasing this for over a year now and I'm out of ideas....
Car has :
Creative Steel Elimivibe engine and trans mounts (little over a year old)
All new drive belts, pullies, idlers, ac compressor, tensioners up front
Trans Fluid Flushed
Things I'm leaning towards at this point :
Creative Steel Mounts are causing the problem (when I called them they disagreed and said they have had zero complaints on this)
Torque Converter Bad (out of balance somehow)
Crank Pulley Bad (it looks good from inspection and doesn't show any excessive wobble while running)
Anyone else have any ideas?
