Throttle Body: Installation

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Ensure that the MAF/IAT electrical connector and the connector seal are properly installed and not damaged.
  1. Install a new throttle body gasket. See Fig 1. Connect the coolant hoses to the throttle body. Install the throttle body assembly. Install the throttle body attaching bolts. Tighten the throttle body bolts to specification. See TORQUE SPECIFICATIONS .
  2. Connect the TP sensor electrical connector. Connect the crankcase ventilation hose to the throttle body. Connect the TAC motor electrical connector. Connect the MAF/IAT electrical connector. Install the air intake duct. Refill and bleed the cooling system. See COOLING SYSTEM BLEEDING  under COOLING SYSTEM.
  3. Check for complete throttle opening and closing positions by operating the accelerator pedal. Monitor the throttle angles, using a scan tool. The accelerator pedal should operate freely without binding between full closed throttle and wide open throttle. Start the engine. Check for coolant leaks.
