Just bough another s55. I am having some issues with the throttle and high rev. when I start the car it will idle high in park and neutral. then it will just go to limp mode with no throttle. I am in Orange county Ca ..there was a guy sseric who seemed to know alot about it..he works for MB just hoping someone can give me some good advice. gonna replace plugs this weekend.
Thanks

throttle?

just glanced thru......... are we talking "throttle valve" or "throttle body"... is it a transmission or engine issue....... I see both mentioned, are both at issue here?
