Hi, can anyone help? Have a 1993 E220 Auto estate, M111 engine. Only 156,000 miles. Sometimes, not all the time, when I pull away the car will hesitate then proceed as normal. This happens only on light throttle, the engine just seems to die, whilst the electronics try their best to keep things running. This can result in surging especially in reverse. Also if I brake heavily the engine invariably dies. This can be a the least embarrasing, at the worst terrifying when the car dies halfway accross a junction. Have given everything a cursory 'going over', and can not see anything untoward. Any advice greatfully recieved.
