Hey all. I need some help. I got ticketed (in Cali) by CHP and had to get my car smogged at a state referee site. I smogged it this morning and it DIDN"T PASS. The only part it didn't pass was the IDLE part. Here are the specs:

At Idle (702 RPM):
%CO2: 9.0
%O2: 7.4
HC (PPM): AVE: 17, MEAS: 101 (this is where i failed-max is 100)
CO (%): AVE: 0.00, MEAS: 0.10 (max is 1.00)

At 2500 RPM (2496 average):
%CO2: 14.5
%O2: 0.1
HC (PPM): AVE: 12, MEAS: 18 (max is 130)
CO (%): AVE: 0.10, MEAS: 0.03 (max is 1.00)

Does anyone have any idea why I didn't pass?? I was told that at idle, there was too much oxygen. Any suggestions? Thanks for all the help.

I live in the great state of Michigan, where you can do anything to your car and get away with it. SMOG is a thing that we don't need to wory about. What happenes if you dont pass your smog test??

ps. Sorry I can't help you out.

If you don't pass smong, you can't register your car. If you can't register your car, you can't drive it. If you get aught driving it without it being registered, you can get ticketed or even impounded.

What type of engine/fuel management do you use? I wonder if you have a "good enough" one, you could lean out the mixture in the 0-2500 rpm range just enough to let you pass.

You only missed it by 1 ppm??

Advance timing and try again.

1ppm? screw that. tell them to test it again lol. Its going to pass either by a little bit or its going to fail by more. No worries.
