Idle Acceleration Stall W124
At my wits end. 1991 300CE with 111K. Gone over vehicle thoroughly replacing worn or suspect parts.............
Here is the situation:
Rough starting warm worse than cold.
Idles around 750 rpm with A/C on or off.
Main concern is stall condition from stop with A/C on. A/C cools fine.
The following items have been replaced in the last 5 months:
Plugs, rotor & cap
Cold Start Valve
All thermo sensors
Any help would be greatly appreciated.
I have not checked the idle control valve yet.....but....how do you adjust the idle? I have adjusted the idle mixture to no avail. I cannot get the same readings with the a/c on as with the a/c off.
