I have a 1985 190E with about 192K on it. I have been having trouble with it for awhile now. It will start up if the car has sat for a while and you give it gas when you turn it over. But you have to keep the accelerator pressed at all times to keep it running and if you let off it will stall out. Then it wont restart after it has stalled until you let the car sit for a long time approx 10 min or more. It is very frustrating. I have recently had my cars plugs, wires, coil, distributor cap, fuel filter, fuel pump relay, and exhaust manifold replaced. I just wanted to know if anyone knew what might be wrong?
