Re: Failed emissions!!!

My car is still failing emissions! However it is definately better 
than before. CO is in control, and HC failed by 0.2!! I dialed in the 
CO as best as I can get it with my dwell meter, its hovering right at 
30, oscillating between 28~32. With my CO dialed in my car idles 
rougher, and is even worse during warm-up, which is why I enrichened 
it in the first place. 

Here some things I have found: the dwell meter reading drops 
considerably when the cooling fans activate. The engine oscillation 
doesnt change, I am sure it just has something to do with voltage 
drops or something. 

Also when the cooling fans activate there is a whining sound from the 
engine somewhere, almost sounds like a vacuum leak, but only when the 
fans are on! 

And finally a question about emissions: Is NOx inversely proportional 
to the HC and CO. It seems that as I decrease CO and HC, the NOx is 
higher, and vice versa. 

Thanks everyone! adam
