Stalling problem. Help please.
Hey guys, been awhile since i posted here but im having a problem thats been getting worse.
My 91 300e 4matic 107,xxx miles stalls at stops after engine warms up. Usually 10-15 min of driving then it will stall randomly when you stop and then try to go.
I suspect it could be a bad sensor, this is because when my dad took the car to be tuned while i was at school the guy steam cleaned my engine. We took the car to two other mechanics and they said it wasnt a engine or tranny problem and it was probably due to the steam clean.
Has anyone else had this problem? Or maybe its because the 4-matic is dying on me? I want to sell the car but i cant sell it while it is in this condition.
This problem started months ago ever since the tune up and it has progressively gotten worse and worse.
Any help/advice is much appreciated, thanks!

dude I'm going through somewhat of a similar ordeal right now.
All the problems started happening yesterday.
Problems:
- Idling issues at a stop while in drive at a red light. Rev will drop below 500RPM.
- Idling issues at a stop while in drive at a red light Rev will jump to 1000RPM then to 0RPM then engine will die.
- Upon accelleration (freeway driving for example) between 3,200-4,000RPM between shifts on half full throttle car will have hard engine/tranny knock and then proceed to shift to next gear.
- small tiny knock/bump in engine/tranny which you can barely tell once and awhile during constant accelleration at the same speed.
These are all issues I receive once and awhile - it doesn't happen throughout the whole time I drive my car.

lots of cars
Chris - Engine mounts will start messing with how the transmission feels. Also the front flex disc is the one that causes the transmission flares.
Fifth - I washed my engine once and it ran like crap because i didn't dry it. It turned out somehow my EHA valve got messed up.
