    Can you see live data?

    What is actual fuel trim?
    What is voltage from maf?

    Using a paper clip or similar back probe the connector to maf an test

    Should have a battery voltage, ground, 5v reference, signal wire.

    Once found signal wire. See what your reading @ idle and what reads@ full throttle.

    That the mad is operating correctly.

    And that it had correct feeds to it.
    As if that is mud reading that can affect fuel etc.
