Hello, just got back from doing emissions today , and It passed all but the idle emissions part, The Idle Limit was 1.2 and the car got a 1.44 in CO (%) section, Any advise on what way I should approach the the situation at hand? I don't think it needs much to pass, just failed but a couple hairs

High CO means it's running rich.

What set-up do you have? The 350 was put in there by somebody other than the factory, what else did they do?

That is all I know of they did to the engine. 350 Ci

Well, to help beyond that, we'd need to know if it is a stock carburetor, aftermarket carburetor, or what exactly is running the engine.
