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 GM LY7 / Vortec V6 and V8 platforms. Use GM MDI / Tech2 or compatible scanner to perform “Throttle Body Relearn” or “Idle Learn” 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.
