Pearl: We are proud owners of a 1990 560 SEL, W-126 sedan,We are proud owners of a 1990 560 SEL, W-126 sedan, with only 57,840 miles on it. It has always been garaged, and is in very excellent "showroom" condition structurally and mechanically /no rust anywhere. Here is the problem: Cold starting is very difficult, requiring multiple, lengthy starting cycles, with the accelerator pressed to the floor, resulting in a very rough start, which soon settles into a stable, smooth idle of approx. 750rpm. Hot re-starts are no problem, as loon as they occur with shutdown time not exceeding one hour.On the open road and in local driving, the engine is very responsive, powerful, and smooth, with no hesitation. Spark plugs and ignition wires are new. Injectors and injector seals are new. The fuel distributor unit is original and has not been serviced.What is your best diagnostic interpretation, given this information? What course of action do you recommend? Thank you. … read more
