Hard starting for 85 190E

Hi All,

I am having a hard starting problem with my 1985 190E that I can't seem to figure out. When starting the car when it sits overnight or is cold, the car will start briefly and then quickly idle down until the engine quits. After I do this 3 or 4 times, the engine will finally stay running. If I try to give it even a little gas to try to keep it running, it cough's and immediately dies. It will cough and die if I try to give it gas quickly until it is completely warmed up, when it then runs perfectly. Warm starts are no problem. I have replaced the fuel pump, filter, plugs, and air filter with no change. My next guess would be a possible defective coolant temp sensor, but am not familiar enough with these engines to be sure. Any advice would be appreciated.
