My emissions test failed with too much CM so I know Im running too rich. Does anyone know which way I need to turn my Air/Fuel Mixture (IAC) to increase the Air Intake into my engine? I only have 1 free emission test, so I need to decrease my CM level output. Passing is 12, I dyno'd a 12.09 so its not far off. Anyone have any other ideas on how to get it down too?

 

what sort of mod's do you have?

 

Nothing much. Just I/H thats about it.

 

that's really strange for you to fail smog with only those two mods...

if worse comes to worse, just throw on your stock components.

what year is your car?

 

Its a 94, but it bearly failed 12.09 passing is a 12. The problem is that I have NO IDEA on how to make it pass. I know its running rich, but how do I change that?

 

with a stock engine (fuel system wise), it's very strange for it to fail... i'm not sure what to tell you to be able to lean it out any...
