I have a 2001 E320 Wagon. Recently when I go out to start it on a cold morning it starts just fine but, as soon as I place it into gear it stalls. I can restart it just fine, run up the idle but, place it into grear and quits. This continues unless I leave it run for about 4-5 minutes and eventually it catches and moves along just fine. As long as the car is warmed up it does not happen again for the rest of the day. It's only on the first cold start. Any suggestions?
obd2 codes?
if none could be cam sensor or engine coolant temp sensor.
Easy diy's on both,both are critical to cold start indicators to the engines management computer system.

Wow! I never expected such quick response. Thanks guys, I really appreciate your help and interest. There has been no CEL and the vehicle runs beautifully after it warms up. This, it would seem to eliminate the MAF, which would act up while running as well wouldn't you think?
I'm into the diy's and just recently ordered a complete service and repair manual CD. I'll look for the cam sensor and coolant temp sensor. Hopfully the manual, when it arrives, willl assist with testing both as well. I suspect the latter, the temp sensor, but is this actually designed to shut the engine down if not up to operating temp?
it is not the shop cd off of ebay?
The temp sensor acts like the choke from old days,it increases resistance as the engine heats up and tells the signal to the ecu to regulate the fuel required at the temps as it increases to running temp.With ohmmeter test res at harness should decrease as temp rises from a high value in a gradual curve to a low value.Sorry i don't have the exact numbers,but if it does not respond you will see it
Oh Lord,
The wife told me those CD manuals from ebay would probably be crap and don't tell me you are going to take her side! Hopefully they can at least identify were the sensor is located.
Your test with the ohm meter sounds logical and reference to the old style choke was perfect. I'm on my way shortly to look for the sensor and put the meter to it. Will outside temperature have some impact do you suppose on the initial reading? Or, will the curve just take longer to drop in value?
Any idea where to find that sensor would greatly be appreciated as well.
Thanks again,
