Car runs rough/dies after not started for a few days on 1994 Mercedes-Benz S420

After sitting for a week the car ran rough when first started but smoothed out after a couple of minutes. 5 miles later car started running very rough and died. Was hard to restart, it back fired and stalled when I put it in gear.

there are so many things that MIGHT have caused this. you will need a good local shop that specializes in MB to diagnose this problem. this particular car is not a good car for the do-it-yourselfer.

I actually have a similar problem. It runs fine, but if I don't drive it for a couple days it will die and not start. I find if it doesn't start I jump cable it and let it run for 15min, not moving, it does a lot better.
