1984 190E fuel mixture/emssions control
My 1984 190E emmsions systems are not covered in the factory service manual. I cannot find a scource for an accurate diagrams of the emmision control system. My engine ID is 102 861. the manual only goes down to 102 961. Without accurate information how can I reslove the mixture problems I am having? Is there a code storage system in ECU? Where do you start looking to reslove a very rich running engine? Freshly rebuilt, new O2 sensor. Help anybody.
