My s2k (ap1 70xxx milles) is running rich, indicated by the buildup of carbon on the exhaust tips, not the tailpipe. The tips are pretty much covered in black carbon. No engine light so, either it is only running rich slightly (within honda parameters) or a sensor is not functioning (not likely considering there are several different sensors that would detect rich running conditions). Any ideas to make the car run less rich or an actual procedure that will set the original specs on mixing the fuel?
