Then it runs fine(so while its still cold ....when coming to stops or lights.. i have to put it in neutral and give it gas to keep it going or give gas/hold break peddle to keep it going)
now i changed the mass airflow system, put in a new hex key and adjusted the air fuel mixture, the spark plugs, cap and rotor are fine, I changed the overprotection relay and fuse in it.
the cold start valve was changed about 3 years ago.. maybe that is the problem? or the idle control valve? my mechanic and I can't figure out WHY it stalls upon start and idles rough when engine is cold.
any help would be much much appreciated .
Thank you

I am working on 1985 Mercedes 190E 2.3 gasoline engine i replaced the engine after finding the cam lobs worn, however this replacement engine is running rough. the timing i am not able to check as it says somewhere that the 5 degrees before top. i used the dash board economy gauge to adjust the air fuel mixture, as i turned in clock wise till it almost quit running then backed it off till the needle read the highest vacuum. the rpm at this point increased to 900 from 700. if it is supposed to idle at 500, i am in trouble. t has new plugs and all cylinders are firing. I believe my ICV is working and i checked for vacuum leaks. the temperature is just above the 48 on the dash indicator. the engine smooths out as the rpm increases and when i put it in gear reverse or drive the RPM drops.
