I have a 1990 miata that seems to run rich There are no codes and the car runs nice but sometimes after a high speed run the cat stinks probably from being overworked. I have replaced the cat and oxygen sensor but still the same problem. The car failed on an emissions test. The tailpipe is sooty.. Any ideas???
