ETC and SWS error indicator lights, too much accelerator makes ETC light flash and power loss. Four wheel error light, (it goes haywire) starts idling real hard nearly stalls out putting in park. I hooked it up to a few diagnostic tools code p2173. I will attach the pictures.

P2173-High airflow/vacuum leak detected.

The common cause for that code and poor idle is a big vacuum leak, most of the time from a broken fitting or line. I would start by checking every vacuum line and fitting, including the under vehicle EVAP lines. Check the MAP sensor, PCV system and the plastic intake manifold for cracks/holes. Also the brake booster as well.
