my 88 900T w/high NOx failed Georgia Emissions & turned out to be 1) faulty turbo bypass (hooter) valve causing lean to the engine & 2)leaky header pipe causing it to run lean to the cat -didnt have the high HC as well though -did you put her up on a lift to check out the exhaust system for holes/leaks?
