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? |

To almost answer my own question:
Today I spent some time at Barnes & Nobel. There was a softcover book by Motorbooks International, "Bosch Electronic Fuel Injection" or something close that had sections on each type, including the 912E pertinent K Jetronic. Very informative, an easy read. I need the 3mm long key and an exhaust analyzer. Gonna take it to a shop. Thanks for the responses. |
