poor running

hello everyone, i am having a running problem with my 907. its running too lean(at about 2% co) and it will not adjust. i checked the voltage on the 2 wires that come from ECU and there is 12.3v all the time and i dont think it should be that high. i also checked the voltage at the adjuster and it goes from 0 to 5 volts so its ok, if anyone knows what the voltage should be to the injectors that would be great.

thanks and happy new years

Is the TPS set correctly?
The CO adjuster on the ECU don't make any difference?
Are the idle balance screws fully turned in? Fully in gives less air
& richer at idle.
