2005 Mitsubishi Diamante

Hi anyone who can help.

My 2005 mitsubishi diamante was built in Australia.

I'm experiancing a vibration shaking problem, when the car is stationary and idling. The vibrations appear to be coming through the engine, and are very noticeable in drive and lesser in the other gears.

I took it to mitsubishi here in New Zealand and they diagnosed it as engine crank timing incorrect, however another respectable mechanic fixed this, and yet the vibrations continue.

You feel them through the seats, and steering wheel, it doesnt shake when moving only when the car is stationary and engine is warm, when the engines cold its barely noticeable.

Could anyone help?
