Failed Smog Test
I am fairly new to the forum.
I have a 1993 FD that is mostly stock. I have upgraded the radiator and AST only. I bought the car new in 1993 and had the engine replaced in 2007 at 120,000 miles. The car now has 134,000 miles with the original catalysts (both pre-cat and main).
I just failed my smog test by a couple of points. If the old limits were still in place, it would have passed. Here are the readings.
15 mph
HC 61 (max) 60 (measured)
CO 0.36 (max) 0.15 (measured)
25 mph
HC 37 (max) 38 (measured - FAIL)
CO 0.35 (max) 0.41 (measured - FAIL)
What do people recommend to get this to pass? I understand the pre-cat doesn't help much, but would a new cat make this pass? Does someone have "good" one laying around I could use to pass the test? After I pass, I am going to register the car in Imperial county (no Smog tests required).
