When it's cold outside, below -10 dec C sometimes my fathers E240 stalls after starting. Engine actually runs at 200-300 rpm's and doesn't respond tothe gas pedal. Full trottle and it mangages about 1000 rpm's. If you restart it again everything is fine. This has happenede perhaps 5 times in the last two months. Car has done about 60K. Is this a common problem? A friend of mine has a 99 E200 and it has done the same a few times as well.
