Hard Start In cold, when started... dies when gas is applied! HELP?

[Silvia007]

Alright guys, so here I am, with this problem for a while, did searches and done suggestions from similar posts and nothing. What's happening to my 93 240 is that it's quite hard to start when it's cold out. When it starts, it idles but if I apply gas lightly the rpm rises, but if I apply say more then 50% throttle, the car stalls... Not only this, on hot summer days, I would start the car and the first attempt it would stall immediately and then if I start it up again, it runs fine. I'm completely stumped as to what to do next. Any help would be great!
