2001 S600 rough idle....

Been to dealer (Atlanta Classic) several times to complain about rough idle....it is as if the car wiggles at a stop or in park...does this with or without AC on.

They say they have checked everything.....what they mean is I guess they don't know how to fix it!

This V12 was impressive the first 15k, turbine like smoothness and quiet beyond imagination.

A V12 should be super smooth or am I just out of my mind?

Also, starting to get a "whirring" noise on mild acceleration.

Sounds like a bad MAF sensor (Mass Air Flow) ... Have they ever checked/replaced that ?
