1986 Mercedes 190e It runs rough at idle and hard to start At cruising speed it rums pretty good What could be wrong new plugswireso2fuel filter already?
HI, The best thing to do is check the basic issues that could affect starting. You have already changed the plugs, wires and fuel filter. Have you cleaned the fuel injectors with a pint or two of commercial fuel injection cleaner? Dirty, clogged fuel injectors do not give a fine spray of fuel, preventing the engine from starting easily. When the engine is cold it will missfire and stumble. When it is warm it will run better with dirty injectors, but your fuel mileage will be poor. Also, consider a new air filter. Other, more expensive issues are replacements of fuel injectors, mass air flow sensor, and other sensors that measure and regulate the air/fuel mixture, etc. hope this helpsH
