Mass Airflow Sensor, looks like a smaller throttle body that's a screen, measures how much air flows through it. Alerored04 suggested it may be a MAF-related issue, but that's not true.

How exactly did you check for vacuum/intake leaks? Spray starter fluid around connections/hoses/at the intake manifold -> head area and see if the RPMs go up.
