RE: 03 Dodge Ram Hemi question???
ok, for starters, P2106--Throttle Actuator Control System - Forced Limited Power
P2175--Throttle Actuator Control System - Low Airflow Detected
Beyond that, I have no experience with the throttle control system, so I can't help anymore. Hope somebody else can chime in for you or it ends up being a cheap and easy fix.
