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 Opel/Vauxhall GM platforms. Use GM Tech2, OP-COM, or compatible OBD-II scanner to perform “Throttle Body Adaptation” if issues persist. Disconnect the negative battery terminal for 5 minutes before installation. Install a new throttle body gasket (sold separately) and torque bolts to the manufacturer’s specification. 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.
