I recently moved to Las Vegas. A smog test is required, even for classic car plates. The test consisted of two minutes at 2500 rpm, idle, 1000 rpm, idle, 2500 rpm, idle.
The car passed the 2500 rpm CO test of 2.50 with a 2.16. However, it failed the idle test with a 3.44. The tech stated it was idling too rich. The car is a '76 912E with the 2.0. I installed a new K&N filter to maximize air flow. What else can I do to lower the idle CO reading? There is a provision for a waiver, after $450 in repairs at an approved shop. I would like to put the money elsewhere. Help? |

What are the other numbers? If HC and CO are both high, then the tech was right, and you're running rich. High HC would be anything above 150 or so. The alcohol trick may work, but if you get your car running properly, you'll get better gas mileage all the time, not just get it through the test. If you haven't done a tune up recently, have one done now.
