The only way you adjust the mixture is if you're running carbs. Have you got a 316?

Idle mixture can be adjusted slightly on an injected car by varying the bypass port for the AFM door or electronically by a pot. connected to the ECU's lambda sensor input, BUT, it should NEVER need adjusting.
If the CO is out of spec., then there is a fault which needs sorting (usually an air leak or out of spec. injectors). Adjusting the CO control means you are then unlikely to ever get the car running as it should.
For reference, CO at 1% or a bit less is the figure to aim for.
