If you want to tweak your EFI or have just changed the O2 sensor you might
want to "touch-up" the CO adjustment. Here's how:

1- Locate the test connector, for example on my 505 ZDJL car it's the
loose unconnected one on the right inner fender

2 - attach a DVM (digital voltmeter) between that point and ground,
with the car running you should see 7 volts DC or so

3 - adjust the mixture screw pn the side of the air flow sensor to
get a reading of 7 +- 0.5 volts

Note: the mixture screw may have a no-tamper plug if it's never been
adjusted before.
