Rough idle?
Have less than 4k miles and recently noticed rough idle when engine is cold. Outside temp is not low - about 40-60F. The car is shaking up like one cylinder is not firing up.
Anybody else experiencing the same / any ideas or suggestions on what is the problem?

i notice something similar when i start the car. it doesnt happen every time, but every third start or so, it knocks a bit and then goes away within 4-5 seconds. Definitely bringing this up at my next service. Didnt pay all that money to have it sound like a Mitsu diesel in europe
