Is there supposed to be a ball-bearing jammed in my EGR hose?

I have been fighting with my 450SL for about six weeks now trying to get it to idle better in D. It shakes the car in Drive but ok in Park. SO far replaced:plugs, wires, Dist. cap and rotor, additional air valve, fuel filter, Injector seals and holders, checked all vacuum hoses, set timing to TDC, checked fuel Dist. screens. It still idle's pretty rough and hesitates on acceleration. Ay ideas about why the previous owner may have put the bearing in the EGR. IS it supposed to be there I took it out and reconnected the hose and still stumbles on Accel and shakes.

thanks for any help.
