car shudder at idle

[Mugen_Euro]

Hey guy my Euro tends to shudder more occasional than not when warm and at idle, and im talking about a very noticeable shudder. It also tends to shudder when i slow down around the speeds 15 - 0. Their is no shuddering when driving the car though.
The car however doesn't shudder when put in neutral, or when cold. My mechanic said it could eb the spark plugs so i had them changed, now he says maybe the coil pack?

anyone had similar problems?

Hey mate, I have had a few of the cl9 euros with a seized vtec pin in the rocker arms cause exactly what you've described.. On the intake rocker arms.. One vtec rocker arm locks on.. Idles normally but slow creapin speeds it shudders.. Had to remove timing chain, cams and rocker gear.. Pulled appart all rocker arms and cleaned vtec pins.. Perfect afterwards.. What state do you live in?
