Installation must be performed by a professional. After fitting, a throttle body relearn procedure is required to recalibrate the throttle body position sensor baseline — this is standard throttle body service practice for Fiat FIRE 8V platforms. Use Fiat Examiner / Multi-EcuScan for “Throttle Body Adaptation” if issues persist. Non-professionals should not attempt installation, as improper fitting may result in throttle body malfunction. The instruction manual included in the package is for professional reference only.
