W202 C220d misfire/judder problem

[The Ben]

Can anyone help,

My c220 is giving me gip! The butterfly valve is 'fluttering' in the inlet manifold making the car not run correctly, the end result are plooms of smoke out the exhaust and loss of power. It starts doing this when the accelarator reaches a certain point, or certain revs. Usually around 60-70mph in 5th gear... Which is annoying as Im always on the m/way.... grrr

Anyone got any advice as to how I can sort it, if there is a fix or just buy a new unit!!
