On my 1993 300D 2.5 turbo, USUALLY when i start it in the morning after a cold New England winter night the car will start without hesitation, the tach will work perfectly, and the engine will run strong and smooth with perfect accelleration.

After the car is driven for a while, and the engine is at normal operatiing temperature, when i turn off the engine to go into a store and come out 10-15 minutes later the engine will take an extra second-second and a half to start, the tach will rest at zero, the engine will idle a little rougher and the car is extremely sluggish, it feels as though some of the cylinders or the turbo is simply not working, as the car severely struggles to get up to speed and often barely makes it up hills.

Any ideas guys? I'm lost here and want this problem fixed. Thanks for all your help!!
