Hello all.
My 190E 2.3 (injection, 8v, 1992) has an extrange behaviour: The car starts easily when cold, a bit rough but it smooths in 2 or 3 seconds. When I drive the car so it gets warm, if I stop the engine and in the next minutes I restart it again, the idle is extremely low for some time, sometimes it even stalls. This only happens when the car is hot. What can be the cause?

Thanks!
