Hi, does anyone know if a 1993 180e has an oxygen sensor? I'm going nuts trying to determine why this engine is running so rich, badly fouling plugs and stalling intermittently during take off at traffic lights. So far I have replaced fuel pump and filter,crank angle sensor and all spark plugs. I put my hand at exhaust pipe revving above 3000rpm and it's riddled with oil splatter. Engine ran smooth with no hesitation for first 5 kilometers after new plugs were fitted. I think it's possessed and trying to get us killed at intersections! Any help will be appreciated.....
