My 1985 380SE does this too, but mostly in the summer. It will sometimes stall when hot, when coming to a stop, making a low speed turn, or when shifting into gear from a stop. When the engine is cool, or cool outside- it never stalls. However, on the flip side, when it is cold/cool outside- it will have a rough idle (especially when I start it in the morning)- almost missing and will sometimes continue throughout my trip, but only occasionally. I have not checked for air leaks yet. Idle control valve was checked and good though. Funny- when I start it in the mornings and do not press the accelerator- its fine, but when I rev the engine a bit, it starts missing and spluttering. Its been doing this for a year, but I would like to fix it, as it is annoying.
