I have just purchased a 1995 c280 and it has been giving me some trouble. It starts fine but wen i try to pull out it seems to stall especially in colder starts. I try pressing the gas while it is still in park and it either dies or it seems like its going to die but then gets a kick. it seems like its not getting fuel in it until i press the gas but i have no idea. it then seems to lag for a minut or two while driving then it runs fine. It also stalls wen i am trying to reverse or make a u-turn only when i cut the wheel as far as it goes. Why could this be? My idle seems like it also changes while in park. One day it could be at .6 rpm thre next at .8. What could this be?
