Car is running rich

My 1988 Acura Integra is running rich.

It’s fuel injected, and has an ECU, but it does not have an OBDC 2 port.

How do you adjust fuel mix in a car without a carburetor?

Thanks in advance.

The problem is somewhere else, probably a faulty air flow sensor. The ECU is adjusting the fuel according to the info it is picking up.
