When I startup my Mercedes and its cold it shakes, and if I step on the gas it stalls. When I lightly step on the gas and leave my foot there long enough for it to warm up then it doesn't stall. Once it’s warm it’s OK. It only happens when it’s cold. I am also having a problem with my headlights and electrical wiring. When my battery dies, and I get a jump to start it back up the headlights don't work. The regular beams on the driver’s headlight works and the right is weak. And when the high beams are on the passenger light works and the driver’s side doesn't work. It takes a few days of driving for the headlight to work properly again. Do you know what’s wrong and how I can fix it?
