I was very disappointed that my 1978 Alfa Spider failed smog in CA yesterday. I inherited the car six years ago. It failed its first smog (in my possession)miserably, four years ago. Eventually, that was corrected with a new catalytic converter, after which it passed with numbers so low, the man testing it doubted his equipment. Next smog, two years ago, also passed fine, with good numbers. This time, HC very low at 25 and 20 ppm (max allowed is 415 and 365 ppm) and NO low at 59 and 52 ppm (max is 1396 and 1256), but CO is in the gross polluter range, at 5.04 and 5.03 (max is 1.41 and 1.21). What baffles me is that this car has had only about 4,000 miles on it since the new converter (and a top-end engine rebuild), in September 2005. Why would it suddenly go so wrong? Any ideas anyone? What strategies would you suggest? Any help much appreciated.
