why i always have a knocked sound with bad acceleration when i accelerate my mercedes 200E 1992?
i tried to adjust the distributor ,plug checking ,using injector cleaner ,clean air filter and using fuel improvement without any imrovements i finaly found ablack dirt in all heads of plugs and that may be to bad ratio of air to fuel ratio. do i have to make replacements
THe black carbon build-up is an indication of improper air-fuel mixture. With a lot of carbon build up on the valves, and in the combustion chamber, you probably have caused an increase in compression ratio. With the proper ignition timing and the correct spark plug heat range, the air fuel mixture should self adjust until the tail pipe burns clean and free of carbon particles. First check would be to verify the correct plugs and ignition timing. Then you should check the fuel injection unit and exhaust gases for the correct chemistry via a smog check. That would include, O2, CO2, HC, CO, NOx. A malfunctioning Catalytic Converter can also cause this kind of problem and would show failures in the smog check analysis.
