I failed my Emission test today with a 1990 Ford Taurus Wagon. The HC level at 15mph passed but at 25 it was double the limit. The co% failed at both
15 and 25mph (the levels were .42 and .77 the limits are .37 and .53) Finally the NO ppm were really high 2685 and 2617 compared to the limits of 1220 and 1167 respectfully. Any help you all have as to the problem of these failures will save me lots of $$$- posted
