Default Is300 2008 rough idle

Hello guys,
I am back again with a new problem which is bugging me for a while. I have searched a lot on the web but nothing fruitful till now. I have read that is 2nd gen model tend to vibrate while still in D but standstill. It usually happens when the car is cold and once the engine heats up, the vibration reduce drastically. Is there any known solution to this? Local mechanic first suggested to change transmission mount and then spark plug change, both of them are completed but still its happening. Any help is highly appreciated. TIA

And clean the MAF sensor.
How many miles on it? Did mechanic say anything about carbon build up when the plugs were out?

Nope. First time it was transmission mount and 2nd time it was plugs. The car is 190k kms strong. Runs smoothly, no misfire, only when its cold it vibrates.
