Just had my Fiero in for it's mandatory emissions test. Here are the results:
ASM 2525 Idle
| Limit | Reading | Limit | Reading |
HC ppm | 314 | 5 | 300 | 31 |
CO% | 2.49 | 0.00 | 1.50 | 0.15 |
NO ppm | 3298 | 928 | N/A | N/A |
I just put a new cat on last month, and since I was a little worried about passing with the 3.4, I also put some emissions reducing 'juice' in the fuel tank before filling up. I'm not sure what it was called exactly, but it was manufactured by Penzoil. I guess that I would have passed without the 'juice', but being the nervous worry-wart type, I just wanted some extra peace of mind...
