hello everyone,

i have a problem with s320 engine 104. the idle is about 750 if operating temperature is reached and if the lever shifted to D or R it goes down to about 600rpm and never gets back to 750rpm. also, when shifting to D and R the car surges. have any of you in here experience this one? could this be caused by the throttle valve actuator? exhaust(catalyst)? i tried adjusting the idle speed but no reaction on the tachometer. just to add up more information the engine is unstable(shaking). tried cleaning the injectors, replaced spark plugs, MAF. also, i tried to read the fault and the O2 sensor appears to be the faulty one. but all i know is the O2 sensors will just affect the idling. need help form all of you here who have so much experience with w140. thanks in advance.

idle speed contact. replace actuator and its okay now. this is just to update everybody in case you experience the same.
