To fix the ETC (Electronic Throttle Control) on a 5.7 HEMI, start by checking for any stored trouble codes using an OBD-II scanner, as this can pinpoint specific issues. Inspect the throttle body for carbon build-up or damage, and clean it if necessary. Additionally, check wiring and connectors for any signs of damage or corrosion. If the problem persists, consider replacing the throttle body or the accelerator pedal position sensor.
