I was really wary of starting ANOTHER CIS smog thread but...I have questions soooooo here goes...
Okay fellas - after spending most of the day reading through the other smog related threads, including the "Ultimate California Smog thread." I've come to the conclusion that I simply don't know where to start...
I don't have an gas analyzer and I'm not sure I would know what to do with it if I did - other than put it my car's tail pipe.
I have an '80SC that I know has mixture problems. I've had it through smog once before and the mechanic I have taken it to in the past got it through after many tries via trial and error.
I don't want to go through that much trial and error again, I want to fix it. This process isn't going away and I don't really want it to be the struggle that it has been to continue.
Here are my numbers;
With the high HC and high NO and very low CO I'm leaning towards the notion that my mixture is too lean.
With all I've read - I honestly haven't seen much mentioned about the Hydrocarbons so I'm a bit at a loss.
Failing all else - I am not averse to taking it to a shop to get fixed I just want to find a shop that can find the problem by investigation rather than parts changing at my expense. It seems either way I end up paying for the hours...
