Your O2 sensor might be clogged up, resulting in a lean reading to
your ECU.  Try disconnecting your O2 sensor wire from the ECU and
seeing if this resolves the problem.

How did you check your airflow meter to see that it's good?  Did you
calibrate it with some type of emissions device, or a known good O2
sensor?
