Hi guys, i have a 1996 c220 with a manual transmission, it has newer spark plugs, wires and a new maf sensor, throttle body has been cleaned too and it has a new fuel pump as well.
here is my problem, the car iddles fine a 750 rpm, no rough iddle at all. But once i am driving and get to a red light or a stop, and hit the clutch, the rpms drop down to nearly stalling the car, some times stalls de car. it only happens when driving and when clutch is on to get to a stop.
what can it be? does my car has a iac valve? if it does, where is it?
i will really appreciate any help you guys can give me. thanks in advance

 

Hello and welcome to the forum! If your car is OBDII, I would recommend pulling the codes - this should give you a pretty clear indication as to where the issue is coming from.

 

Hi, thanks for your response but, here in my home town nobody has the scanner for my car, it is a round shaped port with a lot of holes and, even though a mechanic friend of mine has the correct connector for that port, the scanner doesn't have the w 202 data on it, so, its useless.
do you know if my car has a iac valve?

 

Hello - the older MBs don't have an idle air control valve - the round port with a lot of holes means that it's an OBDI car.
