Hi all. Hope the New year is being good to everybody. I work this site for all I can and have read every question that pertains to my particular car and have gained so much knowledge. I am grateful to Mercedessource for providing this great data base. That said my question is, that if I set my CC at about 62 mph and around 3000 rpm it works fairly consistant. I say "fairly consistant" as eventually it gets a little jerky. If I don't set it right around those values it runs even more jerky. It surges and then backs off again and again as it tries to compensate for rises and dips in the highway. I have read about the amplifier under the dash and loose ball sockets in the linkages. Has anyone had similar symptons and addressed this specific quirk and what was your experience and outcome.
Thanks for any input.
Mike G.
